The thriving business case of residential photovoltaic systems in combination with battery storage systems and other flexibility options, such as heat pumps, leads to additional questions for PV network integration and increases the complexity of planning processes for all involved stakeholders – especially for investors and distribution network operators. In this thesis mixed integer linear and bilevel optimization models are developed for evaluating the interdependencies between these stakeholders and their strategic decision making. A case study-based approach allows assessing how different incentives impact sizing and operation of PV battery storage systems, their network integration and their complementarity towards other flexibility options for improved sector coupling. The analysis of the case studies underlines the importance of using multi-stakeholder optimization models. Appropriate incentive setting and sector coupling decelerate emerging self-reinforcing processes between higher network charges, larger system sizes and inefficient PV network integration. Furthermore, curtailment limits and peak charges help activating a network-supporting operation of battery storage systems and other flexibilities.

This book focuses on the interaction between different energy vectors, that is, between electrical, thermal, gas, and transportation systems, with the purpose of optimizing the planning and operation of future energy systems. More and more renewable energy is integrated into the electrical system, and to optimize its usage and ensure that its full production can be hosted and utilized, the power system has to be controlled in a more flexible manner. In order not to overload the electrical distribution grids, the new large loads have to be controlled using demand response, perchance through a hierarchical control set-up where some controls are dependent on price signals from the spot and balancing markets. In addition, by performing local real-time control and coordination based on local voltage or system frequency measurements, the grid hosting limits are not violated.

Energy systems are encountered in daily life, whether through smartphones, laptops or cordless tools. Cars using fossil fuels are being replaced with electric and battery powered drives, and storage solutions are being implemented to better integrate renewable energies into the grid. Energy Storage Systems introduces the different storage technologies available today. It begins with mechanical and electrical storage and describes in detail electrochemical storage technologies such as lead and lithium-ion batteries. However, this book aims to explain not only what storage technologies exist but also how these storage technologies are applied in storage systems. Therefore, this book provides a short introduction to requirements management and system engineering to explain how storage systems are designed. Furthermore, the book explains the most important power conversion techniques. The technologies presented are applied in many application examples throughout the book and range from solar power storage systems to battery supported mobile phone masts and commercial vehicles equipped with a hybrid drive system.

In recent years a rapid growth in the interest in self-consumption of electricity generated by distributed electricity generation technologies such as rooftop photovoltaic (PV) systems has been observed in the residential sector. Due to this development, future residential house energy systems will face an increased complexity with respect to operation, system configuration and sizing of generation and storage technologies. In this thesis, a mixed integer linear programming model for the integrated operation, configuration and sizing of house energy systems is developed and discussed with respect to its applicability to the specifics of self-consumption in residential dwellings. The conducted scenario analysis shows, that over a wide range of assumptions, PV is a robust measure to decrease the total cost of ownership for heat pump and gas boiler based house energy systems. The existence of a feed-in-tariff and the electricity price structure have a much larger influence on the results than the energy price development. A feed-in-tariff generally incentivizes larger PV systems with higher levels of self-sufficiency, whereas small demand-driven PV systems with high levels of self-consumption are favored in absence of a feed-in-tariff. Overall, the proposed model is regarded as applicable for the identified minimum flexibility requirements for the employed generation technologies. The results from the scenario computations provide a clear and robust picture of the role of electricity generation technologies and flexibility options for future house energy systems.
