Integrated Hydropower Storage Systems
National Renewable Energy Laboratory (NREL) engineers are investigating the potential for Run-Of-River Hydroelectric Power Plants (ROR HPPs) to integrate with the electric grid. The project explores the control and integration of energy storage systems based on advanced power electronics, cohesive response to network events, and the interaction of multiple ROR HPPs with the grid. The overall project objective is to investigate and demonstrate the potential for Run-Of-River Hydroelectric Power Plants to participate in ancillary service markets. Control and integration of Energy Storage Systems based on advanced power electronics, cohesive response to network events, interaction of multiple ROR HPPs with grid, and its equivalence to a large HPP are other objectives of this proposal. Additionally, the project includes collaborating with power electronics Original Equipment Manufacturers on an emerging technology to maximize ROR HPP operation that leads to for flexible grid services.
