GEMS: variable-Generation Energy Management with Storage

One of the exciting topics we’ve been working on is algorithms and models related to energy management, where uncertainty is a crucial element in the process. In particular, our focus is on building decision support tools for optimal storage management when a variable and intermittent energy source is used.
This project combines machine learning methodologies and stochastic optimization tools to develop optimal energy management systems for a system with photovoltaic generation, interconnection with the grid, and energy storage. If no storage is available, the decision is simple: if the generation is larger than our demand, we sell to the grid. Otherwise, we need to buy from the grid. However, when storage is present, the decision is more complex. Should we store the energy for future usage? Or maybe tomorrow, we will have a large surplus of energy that allows us to use the energy today, at a time when the price is high. When is the best time to sell, store, or use solar energy? We answer these questions through our research project by developing a prototype that implements the optimal decisions defined by our mathematical optimization models and measuring this approach’s benefits compared to today’s standard storage policies.
