摘要
光储型电热协同系统的日前运营决策会影响次日系统运行的经济性、可靠性和环保性,制定合理的运营决策计划意义重大。针对传统决策制定方法所存在的指标赋权合理性不足、未考虑信息灰性以及模糊性等问题,提出了基于灰色模糊评价的日前运营决策方法。首先,为提高指标权重的合理性,采用最小叉熵法求解考虑主、客观权重内在联系的综合权重。其次,为减小信息灰性以及模糊性对方案评分结果的负面影响,构建了面向光储型电热协同系统的灰色模糊评价模型,并基于该模型设计了日前运营决策算法,从而获取次日系统的最佳运行方案。最后,以一个工业园区光储型电热协同系统为例进行了仿真验证,结果表明所提运营决策方案可改善系统运行的经济性、可靠性和环保性。
The day-ahead operation decision of the electric-thermal system affects the economy and reliability of the next day's system operation.Therefore,it is significant to develop a reasonable operation decision plan.To solve problems of the traditional decision making method,such as the insufficient rationality of index weighting and the failure to consider the grayness and fuzziness of information,a day-ahead operation decision making method based on grey fuzzy evaluation is proposed.To improve the rationality of index weights,the minimum-cross entropy method is used to obtain comprehensive weights that consider the intrinsic connection between subjective and objective weights.To reduce the negative impact of information grayness and expert scoring ambiguity on the solution scoring,this paper constructs a grey fuzzy evaluation model for the electric-thermal system and designs a day-ahead operation decision algorithm based on this model.Finally,this algorithm is used to develop a day-ahead operation decision scheme for an electric-thermal system located at an industrial park.The results show that the operation decision scheme can improve the economy and reliability of the system.
