摘要:
Shared-energy storage (SES) can break the energy interaction barrier between the demand side and the supply side, which is becoming an option for improving the flexibility of energy systems. This study designed a novel structure for the shared-energy aggregator (SEA), incorporating a microgrid (MG), prosumer and SES. Then, a two-level market transaction optimization model for SEA, considering the robust stochastic optimization method, is proposed; namely, at the day-ahead stage, a robust stochastic operation optimization model is constructed to achieve the dispatching plan from the demand side under the objective of achieving the minimum energy consumption cost for the prosumer, and at the real-time market stage, a robust stochastic operation optimization model from the supply side is constructed to arrange the optimal dispatching strategy under the objective of the maximum aggregator benefits of MG and SES. Finally, an industrial park micro-grid in Qinghai Province, China, is selected as an example for analysis.
