博弈论在光伏并网鲁棒优化调度问题中的应用

摘要

With the increasing scale of photovoltaic power,its fluctuation and randomness will bring a lot of difficulties to the optimization scheduling of power system. In view of the uncertainty of photovoltaic power output,a robust econom-ic dispatching scheme for the power system incorporating photovoltaic power stations is proposed based on a two-person zero-sum min-max game model. The model aims at minimizing the highest costs which the worst scenario causes. With the dispatchers and the natural enviroment being the bilateral game players,based on the robust optimization model, an economic dispatch strategy for photovoltaic pouer stations are investigated by solving the corresponding min-max model. Finally,the simulation results demonstrate the rationality of the proposed model and algorithm.%随着光伏电站并网规模不断增大,其出力的波动性和随机性给电力系统优化调度带来很大的困难和挑战.针对光伏电站出力的不确定性,基于博弈论的思想建立了含光伏电站的电力系统鲁棒经济调度问题的二人零和博弈min-max模型,该模型以最小化最坏场景带来的最大运行成本为目标,以电网调度人员和大自然为博弈双方,求解该min-max模型得到针对光伏电站出力不确定性鲁棒性较强的调度策略.最后通过算例仿真验证所提模型及算法的合理性.
