During the preparation of this dissertation, the applicability of parametric identification mathematical models was extended in the field of electric power systems control. The dissertation presents algorithms for ensuring frequency stability in hydro generators units and power generation module systems, which include frequency containment reserve and synthetic inertia algorithms. Using these algorithms, low-order continuous transfer functions were developed, which can be applied in practice and implemented in controllers. By utilizing mathematical models of the electric power system, the issue of active power “pit” in hydroelectric units was investigated, and an algorithm was developed to ensure frequency stability. This algorithm enables hydroelectric units to meet the frequency reserve activation requirements set by Commission Regulation (EU) 2016/631. Furthermore, using the mathematical model of a synchronous generator and applying parametric identification mathematical models, the synthetic inertia algorithm was developed, along with the identification of the synthetic inertia transfer function. The input signal for this synthetic inertia transfer function is the change in system frequency, while the output signal is the active power that corresponds to the inertia created by synchronous generators. Mathematical modeling demonstrated that when this synthetic inertia transfer function is implemented in the control system of power generation modules and connected to the electric power system grid, the power generation module will inject active power to the electric power system at the initial moment of disturbance. This active power will be equivalent to the inertia generated by the synchronous generator, thus contributing to stability and reliability of the electric power system. Notably, the developed synthetic inertia algorithm takes into account the inertia coefficient H, allowing the obtained synthetic inertia to be measured in seconds, analogous to the measurement units of synchronous generator inertia.

Annotation:
This scientific work investigated how environmental factors (air temperature, CO2 concentration, soil moisture content) affect the efficiency of bioremediation of heavy metals in soil. By applying two different methods – phytoremediation using energy plants (industrial hemp, summer rape) and vermiremediation with compost earthworms – experimental studies on the remediation of single heavy metals and their mixtures were carried out. The tolerance of organisms to soil heavy metal pollution and the underlying mechanisms (biochemical, physiological and genetic) regulating biological remediation were evaluated. The energy potential of plants, various parameters of heavy metal bioaccumulation (metal concentration in different parts of organisms, bioconcentration and translocation coefficients, total accumulated amount), theoretical remediation time, and soil cleaning efficiency were analyzed. The findings show that by regulating the environmental conditions, properly selecting the species and the duration of the process, it is possible to ensure a sustainable and effective bioremediation. It has been proven that summer rape is a suitable species for phytoremediation of heavy metals under changing environmental conditions, and compost earthworm is a suitable species for phytoremediation of soil heavy metal mixtures while maintaining optimal environmental conditions.

Annotation:
The need for knowledge on the separated flow dynamics and structure in channels with sudden cross-section changes is decided by wide practical application while designing various reactors, combustion, mixing, flow and meter measuring chambers. The problem is closely related to the flow control problems, where the influence of inlet, mixing and outlet conditions on mass and heat transfer processes must be solved. The main goal of this work is to investigate the flow controlled by pulsations, roughness elements and geometrical parameters using experimental and numerical methods, while identifying the parameters determining the recirculation zone dynamics and the separated flow structure in cavities. In this work, the advanced flow visualization methods (micro and macroPIV) applied in the experiments are combined with numerical modelling, allowing to simultaneously observe the average and instantaneous velocity distribution and determine the mechanism of changes in the flow structure and its influence on the mass transfer process efficiency. The research results and analysis presented in the dissertation complement the fundamental knowledge on flow control methods and their influence on the flow structure and the recirculation zone length variation regularities. The revealed regularities in the recirculation zone development during the pulsation cycle are linked to the separated flow average structure and allow to explain the behaviour of additional vortices. The influence of the pulsatile flow on turbulence intensity has been established, which reveals the origin of velocity fluctuations, while the established dependency of velocity distribution and pressure loss on the roughness elements configuration provides an opportunity to define the factors determining the efficiency of flow control.

Annotation:
Due to the increasing human population (6.97 billion in 2010, 7.82 billion in 2020), the demand and consumption of various consumer goods/products and the amount of generated waste are increasing. The need for public authorities to provide sufficient and sustainable waste management and disposal services is becoming increasingly important. EU waste management is based on the waste hierarchy principle (Directive 2008/98/EC). According to this directive, the aim is to reduce the amount of waste by reusing or recycling it. However, not all waste can be recycled or reused. Recycling or reusing waste also has a limited life cycle; after that, it must still be disposed of. At this stage, there is an opportunity for sustainable waste management through applying plasma gasification, where secondary higher-added value products (e.g., synthetic gas) are obtained from unsuitable reused or recycled waste while avoiding the formation of harmful secondary pollutants. These products can provide additional benefits in the further production of various chemicals, biofuels, electricity or thermal energy. The performed experimental research on solid waste (wood, refuse-derived fuel, and polypropylene from FFP2-type respirators) conversion using thermal plasma allowed determine the influence of the plasma-forming gas (water vapour) flow on the waste conversion process. The efficiency of the proposed plasma technology was also evaluated by calculating the energy and mass balance of the plasma gasification process for each selected material.

Annotation
Households account for about 70% of all greenhouse gas emissions through energy use, but their potential contribution and position in climate policy is not well understood. One of the main challenges in the formulation of climate change mitigation policy is balancing the benefits of climate change mitigation with long-term and globally shared public goods such as energy efficiency and the use of renewable energy resources. Energy consumption and conservation, use of renewable energy resources and other climate change mitigating actions are related to consumer decision-making and behaviour. The promotion of these actions must be linked to the idea that reducing greenhouse gas emissions is beneficial to society. Determining the preferences of all stakeholders is also critical to creating the right initiatives. As a result, insights from behavioural economics can help shape politics by explaining how people evaluate options, make decisions, and change behaviour in the area of climate change mitigation. The main goal of the dissertation is to create a model for assessing the benefits of climate change mitigation measures in households and to determine the most appropriate measures. These measures and the methods for evaluating their benefits in the dissertation are analysed based on insights from behavioural economics. The created benefit assessment model was verified by conducting empirical research in Lithuania. This allowed for the identification of the most appropriate climate change mitigation measures in households, based on the preferences of all stakeholders, as well as the results of the assessment of external benefits and effectiveness, economic efficiency and efficacy.

Annotation
This research investigates the potential of wind energy in expansive urban environments, with a focus on the impacts of climate change. The research introduces an innovative method for calculating wind energy variations within such environments, providing a novel approach to understanding and predicting wind behavior in urban areas. The findings demonstrate that extensive urban development significantly reduces wind energy potential due to increased surface roughness and obstructive structures. Additionally, the study reveals that climate change exacerbates these negative effects, further diminishing wind energy resources. This comprehensive analysis is pivotal for the development of sustainable energy solutions. A new wind power generation model has been developed from this research, designed for use in environmental impact assessments and the strategic siting of new wind farms. The model effectively quantifies potential energy losses in turbine environments, considering both anthropogenic climate change and urban expansion. This advancement provides a critical tool for policymakers and urban planners aiming to optimize wind energy utilization and mitigate the environmental impacts of urbanization and climate change.
JPs e3s & ESI – Joint workshop on Sustainability in Energy Systems
4th june 2024, Lithuanian Energy institute, Breslaujos st. 3, LT-44403 Kaunas, Lithuania.
A central aim of the energy transition is not only to achieve climate-neutrality, but also that the future energy system is sustainable. Today, energy systems models (ESMs) are the dominant tool used for the model-based construction of energy scenarios aimed at providing policy advice to achieve climate-neutrality typically by the middle of the century. However, in most cases the models used minimise total system costs under different decarbonisation constraints and, more generally, focus on techno-economic aspects, i.e. they fall short in considering sustainability aspects in a wider sense. A comprehensive sustainability assessment of the resulting scenarios and energy systems is typically missing and, in the few cases where it is carried out, the scenarios typically perform poorly with respect to sustainability criteria beyond global warming potential since these criteria are not taken into account in the scenario construction. As a result, the produced scenarios and systems lack practical feasibility.
This one-day workshop is aimed at discussing the methodological challenges and possible solutions to provide the required pre-conditions to develop sustainable energy systems and transition scenarios from a holistic perspective. Therefore, the focus will be on multidisciplinary approaches, which are suitable for considering environmental, economic and social aspects as well as their cross-impacts and for dealing with the target conflicts that arise inevitably. The aim is to summarise the possible solutions and research requirements discussed in a white paper.
This is a roll-up-your-sleeves workshop. Participants are encouraged to present a poster at lunchtime, which should focus on possible contributions to the topic of the workshop (solutions for constructing transition scenarios towards sustainable energy systems more holistically). Potential posters should ideally address at least two of the following topics:
Participants interested to present a poster should send a poster title to m.menon@eera-set.eu and g.botton@eera-set.eu by April 30th 2024 at the latest.

Annotation
Understanding evaporation/condensation processes at the nanoscale is crucial for the development of micro- and nanoflow technologies. However, experimental assessment of these processes remains challenging due to the difficulty in measuring the specific process conditions in the Knudsen layer adjacent to the evaporating/condensing liquid surface. In this thesis, the evaporation/condensation processes in the Knudsen layer were studied using the molecular dynamics simulation method, which allows to evaluate these processes at the molecular level and to calculate the process coefficients directly from the molecular fluxes crossing the liquid-vapor interface. From the molecular dynamics simulations, the dependence of the water condensation coefficient on the energy of the condensing vapour molecules was evaluated and the energy characteristics of the water molecules crossing the interface layer were determined. Also, in order to specify the molecular dynamics modelling methodology of evaporation/condensation processes, a study of the impact of the temperature control strategy in steady-state virtual vacuum simulation on the spontaneous evaporation rate and corresponding evaporation coefficient was performed.
