Two-Stage Stochastic Optimization of a Virtual Power Plant | Energy In A Flash

We propose two profit-maximizing operating strategies for a virtual power plant that aggregates electric vehicle chargers with vehicle-to-grid support and local solar systems, and trades in day-ahead and imbalance electricity markets. Both strategies solve a two-stage stochastic optimization problem. In the first stage, hourly energy bids are placed in the dayahead market by solving a mixed-integer linear program, given the VPP’s predictions for the next day. In the second stage, decisions with respect to charging or discharging EVs are made sequentially for every hour, and adjustments to the day-ahead commitments are settled in the imbalance market. The first strategy employs a heuristic algorithm that finds a feasible charging schedule for each EV while maximizing the VPP’s profit. The second one utilizes a soft actor-critic reinforcement learning method with a differentiable projection layer that enforces constraint satisfaction.

More than 130 researchers, 600 graduate students, post docs and other highly qualified personnel in nine faculties are studying the energy transition in over 90 different projects. Our researchers seek to develop energy technologies of the future, improve today’s energy technologies, and understand the transition between the two. We are also studying the effects of energy transition on society, the economy, and the environment. Broadly speaking, we can simplify this complex system into four broad categories: -Energy generation, harvesting, and production -Transport, storage, and access -Use, impact, and regulation -Monitoring, management, and mitigation Through our Energy in a Flash Lightning Research Speaker Series, we will explore all four of these categories, and see how broad and diverse our energy systems truly are.
