Hosting Capacity Assessment Strategies and Reinforcement Learning Methods for Coordinated Voltage Control in Electricity Distribution Networks: A Review

Publisher: MDPI AG

Date: 03-2023

DOI: 10.3390/EN16052371

Abstract: Increasing connection rates of rooftop photovoltaic (PV) systems to electricity distribution networks has become a major concern for the distribution network service providers (DNSPs) due to the inability of existing network infrastructure to accommodate high levels of PV penetration while maintaining voltage regulation and other operational requirements. The solution to this dilemma is to undertake a hosting capacity (HC) study to identify the maximum penetration limit of rooftop PV generation and take necessary actions to enhance the HC of the network. This paper presents a comprehensive review of two topics: HC assessment strategies and reinforcement learning (RL)-based coordinated voltage control schemes. In this paper, the RL-based coordinated voltage control schemes are identified as a means to enhance the HC of electricity distribution networks. RL-based algorithms have been widely used in many power system applications in recent years due to their precise, efficient and model-free decision-making capabilities. A large portion of this paper is dedicated to reviewing RL concepts and recently published literature on RL-based coordinated voltage control schemes. A non-exhaustive classification of RL algorithms for voltage control is presented and key RL parameters for the voltage control problem are identified. Furthermore, critical challenges and risk factors of adopting RL-based methods for coordinated voltage control are discussed.

Cooperative Control of Microgrids: A Review of Theoretical Frameworks, Applications and Recent Developments

Publisher: MDPI AG

Date: 12-2021

DOI: 10.3390/EN14238026

Abstract: The development of cooperative control strategies for microgrids has become an area of increasing research interest in recent years, often a result of advances in other areas of control theory such as multi-agent systems and enabled by rapid advances in wireless communications technology and power electronics. Though the basic concept of cooperative action in microgrids is intuitively well-understood, a comprehensive survey of this approach with respect to its limitations and wide range of potential applications has not yet been provided. The objective of this paper is to provide a broad overview of cooperative control theory as applied to microgrids, introduce other possible applications not previously described, and discuss recent advances and open problems in this area of microgrid research.

Innovation in Sustainable Solar-Powered Net-Zero Energy Solar Decathlon Houses: A Review and Showcase

Publisher: MDPI AG

Date: 16-04-2021

DOI: 10.3390/BUILDINGS11040171

Abstract: Solar Decathlon is a showcase of cutting-edge residential buildings containing innovative solutions and technologies. This study reviewed, identified, and categorized technological innovations from past Solar Decathlon competitions. The review was based on publicly available data of the top five houses from each U.S. and international Solar Decathlon competition. The most prolific innovations identified were from building services systems and architectural design and construction. It was observed that most innovations within building services systems were in heating, ventilation, and air-conditioning, and home automation, while architectural design and construction innovations focused on building adaptability, façade, structure, and building materials. It was found that although there is no fixed relationship between the numbers of innovations in the houses and their overall competition points, there is a high probability for an innovative house to be placed within the top five houses. This study also provides information about technological innovations within Solar Decathlon houses and offers an innovation classification scheme to guide Solar Decathletes to understand what innovations could be implemented in their future entries.

Preliminary Evaluation of the Impact of Sustained Overvoltage on Low Voltage Electronics-Based Equipment

Publisher: MDPI AG

Date: 19-02-2022

DOI: 10.3390/EN15041536

Abstract: Low voltage devices connected to public electricity supply networks can be subjected to a wide range of voltage quality, including sustained overvoltage. Assessing the impact of sustained overvoltage on devices connected to the distribution network is important in determining the appropriate variance of standard voltage levels without unduly impacting the utility and customers from a technical and economic perspective. Therefore, a clear understanding of the impact that sustained overvoltage has on the lifetime of the connected equipment is a necessary task. This paper investigates the impact of sustained overvoltage through a series of accelerated-life testing experiments on a custom designed test device representative of a common interface between the power supply and distribution network, a switch mode power supply. The switch mode power supply with combined rectifier and filtering capacitor represents one of the most common front ends of LV equipment in modern appliances, and the work here concentrates on the impact of overvoltage on capacitor ageing. The results of the testing indicate that there is an accelerated ageing impact correlated with the applied voltage magnitude. Furthermore, analysis shows that mismatches between appliance voltage rating and sustained network voltage, leading to accelerated ageing, may result in premature device failure without the consumer being aware of the root cause.
