Method & Evidence

AimHow can an optimized battery energy storage system control strategy mitigate financial risks and reduce energy costs for distribution companies facing uncertain demand and renewable energy generation?

MethodOptimization modelling and simulation

ProcedureThe study developed a two-level optimization framework for BESS operation. The first level optimizes day-ahead operations considering forecast uncertainties, while the second level manages real-time operations to bridge the gap between forecasted and actual demand. This involved short-term load, wind power, and solar power forecasting, followed by a comparison of purchase strategies under uncertain versus certain demand scenarios.
