摘要
需求侧响应作为解决微电网源荷不匹配的有效方案,提高其响应效率,能够有效地从用户侧改善负荷曲线,提高源荷匹配性。然而,除经济因素以外,需求侧响应实际参与程度极易受到用户心理等不确定性因素的影响。为此,在考虑各种源荷不确定性的基础上,为了充分利用需求侧资源,该文建立一种在需求侧响应中考虑用户心理因素不确定性的微电网鲁棒优化调度模型。根据负荷类型的不同,分别建立基于价格和基于激励的需求侧响应方案,对于其中居民普通负荷和电动汽车负荷的激励型需求侧响应模型,通过引入禀赋效应和环保意识来描述用户心理因素的不确定性。然后,利用列和约束生成算法求解优化模型,得到最恶劣场景下的最优微电网经济调度方案。最后,通过算例分析验证所提模型以及求解方案的有效性,结果表明,考虑用户心理因素不确定性可以有效提高微电网系统运行的经济性和鲁棒性,并为微电网运营商针对性提高需求侧响应参与度提供一定的参考,同时通过调节不确定性参数的取值,运营调度人员可以在经济性和稳定性之间进行合理选择。
As an effective solution to solve the mismatch between source and load of microgrid,demand-side response can improve the degree of response,which effectively improves the load curve from the user side and enhances the matching of source and load.However,in addition to economic factors,the actual degree of participation in demand-side response is also easily affected by uncertain factors such as user psychology.Therefore,on the basis of considering various source and load uncertainties,in order to make full use of demand-side resources,a robust optimal scheduling model for microgrids that considers the uncertainty of users'psychological factors in demand-side response is established.According to the different load types,price-based and incentive-based demand-side response schemes are established respectively.For the incentive-based demand-side response model of residents'ordinary load and electric vehicle load,the endowment effect and environmental protection awareness are introduced to describe the different psychological factors of users'certainty.Then,the column and constraint generation algorithm is used to solve the optimization model,and the optimal microgrid economic dispatch scheme in the worst scenario is obtained.Finally,the validity of the proposed model and solution scheme is verified by numerical example analysis.The results show that considering the uncertainty of user psychological factors can effectively improve the economy and robustness of microgrid system operation,and provide some reference for microgrid operators to improve demand-side response participation in a targeted manner.Meanwhile,by adjusting the values of uncertainty parameters,operators can make a reasonable choice between economy and stability.
