In response to climate change, electricity networks are transitioning from conventional power generation methods based on fossil fuels to renewable energy-based generation methods. However, the intermittent and non-dispatchable nature of some common renewable energy generation such as photovoltaic (PV) generation may restrict the ability to fully exploit their merits. Energy storage systems are used to overcome those challenges and exploit the benefits of PV energy systems efficiently. Community energy storage systems (CESSs) are an emerging type of energy storage system, that can trade energy with multiple prosumers, consumers, and the grid to economically and/or technically benefit multiple stakeholders.
The problem of optimal sizing and placing of a CESS is typically addressed from the perspective of only one type of stakeholder – either the CESS provider or prosumers. In this context, the result of this problem always maximizes the economic benefits of only one type of stakeholder, leaving aside the other. A solution to address this issue is to solve the problem in a multi-objective framework, where the benefits of installing a CESS can be distributed fairly among all stakeholders, meaning among the CESS provider and the community of prosumers. Moreover, PV generation and real and reactive energy consumption of prosumers involve uncertainty, which also needs to be considered to better plan a CESS. Also, it is imperative to value the energy trade through a CESS to avail its beneficiaries.
This talk explores how a multi-objective stochastic optimization framework with a properly selected CESS provider’s energy pricing scheme can help decision makers such as utilities, energy regulators, and community leaders to identify the trade-offs between competing objectives, and thereby benefit all stakeholders equitably.
