This thesis analyzes the technical and economic potential of autonomous voltage control strategies for improving distribution grid operation with high shares of photovoltaic (PV) generation. Key issues include: The simultaneity of local photovoltaic generation and local consumption as well as its influence on reverse power flows.The theoretical potential of autonomous voltage control strategies to increase a grid’s hosting capacity for additional photovoltaic generation.Stability analyses of a voltage-dependent combined active and reactive power control strategy for photovoltaic inverters.The cost savings potential (CAPEX & OPEX) of autonomous voltage control strategies, compared to traditional grid reinforcement measures. The results suggest that autonomous voltage control strategies can be used to improve the technical and economic distribution grid integration of PV systems. If applied appropriately, these strategies are capable of deferring grid reinforcement measures and hence shifting investment costs to future points in time. Of all investigated autonomous voltage control strategies, the on-load tap changer voltage control and a combined Q(V)/P(V) PV inverter control strategy showed the most promising results, from a technical and an economic perspective.

This thesis is about the design and the implementation of a resilient grid operation for the distribution grid. This research question is induced by the advancing of three trends: Decarbonisation, decentralisation and digitalisation. These three trends transform the hitherto passive distribution grid into an active system that contains an active operation. The term “resilience” describes capabilities of the system to absorb, to adapt, and to recover from faults and disturbances. This concept is realised on the one hand with the choice of the operation architecture, on the other hand for the choice of possible methods and functions. This thesis develops a distributed-hierarchical operation architecture. For this architecture several methods have been developed that optimally benefit from the operation architecture and that allow the fully automated operation of the distribution grid. For that purpose a heuristic optimisation has been developed to solve problems like voltage profile violations and congestions. Another important method, especially with regard to resilience, is the self-healing capability to resupply clients after permanent faults.

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.

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.
