一种求解储能系统最优报价问题的改进代理方法

An Improved Surrogate Method for Solving the Energy Storage Optimal Bidding Problem

Yue Chen, Wei Wei, Tongxin Li, Yunhe Hou, Feng Liu, João P. S. Catalão

摘要:

预计储能将在缓解可再生能源日益普及带来的变化方面发挥越来越重要的作用。本文研究了半集中式市场中储能单元的最优报价问题。储能单元向运营商提供其可用的存储容量和最大充电/放电速率;然后运营商通过最小化总成本来清除实时市场。能量存储单元以位置边际价格(LMP)支付/收费。该问题可归结为一个下层为混合整数的双层最优化问题。针对这一问题,提出了一种改进的基于代理项的时空熵联合方法。数值算例表明了该方法的可扩展性、高效性和准确性。

英文摘要:

Energy storage is expected to play an increasingly important role in mitigating variations that come along with the growing penetration of renewable energy. In this paper, we study the optimal bidding of an energy storage unit in a semi-centralized market. The energy storage unit offers its available storage capacity and maximum charging/discharging rate to the operator; then the operator clears the real-time market by minimizing the total cost. The energy storage unit is paid/charged at locational marginal price (LMP). The problem casts down to a bilevel optimization problem with a mixed-integer lower-level. An improved surrogate-based method with the combined spatial-temporal entropy term is developed to solve this problem. Numerical examples demonstrate the scalability, efficiency, and accuracy of the proposed method.
