Parameterized Estimation of Price-response Regulation Willingness of Demand-side Flexibility Resources

中文摘要英文摘要

价格型需求响应可引导负荷侧灵活性资源为电力系统提供调节能力,其调节效果与各资源主体的调节意愿直接相关.然而,该调节意愿具有不可直接获取的特点.为此,从非合作博弈均衡分析视角,提出基于历史用能数据反演的负荷侧灵活性资源调节意愿参数化估计方法.首先,建立负荷侧灵活性资源个体价格响应决策的参数化模型,并基于此构建规模化负荷侧灵活性资源在需求响应中的非合作博弈均衡问题.其次,利用变分不等式和线性规划的强对偶性,将需求响应非合作博弈均衡问题转化为一组线性不等式构成的等价均衡条件.在此基础上,结合调节意愿函数的先验信息构造形式,构造历史用能数据驱动的逆变分不等式,实现负荷侧灵活性资源的价格型需求响应调节意愿参数化估计,并分析其计算效率.进一步,定义调节意愿估计的泛化误差评估指标,并结合不确定性凸优化理论,推导其泛化误差上界,从而从理论上分析了所提调节意愿参数化估计方法的泛化能力.最后,通过算例分析,证明所提调节意愿参数化估计方法的准确性,并探究先验信息准确度在调节意愿估计中的作用.

Price-based demand response(PBDR)can enable flexibility demand-side resources(DSFRs)to provide regulation capability for power systems,and its regulation effects are directly related to the regulation willingness of each resource entity.However,this regulation willingness has the characteristic of being difficult to directly obtain.To address this,a parameterized estimation method of the regulation willingness based on the inversion of historical energy consumption data is proposed from a non-cooperative game equilibrium perspective.First,a parameterized decision model for the price response of individual DSFR is developed,and based on this,a non-cooperative game problem is constructed for large-scale DSFRs to participate in PBDR.Second,by adopting the variational inequalities and strong duality of linear programming,a non-cooperative game equilibrium problem for demand response is then reformulated as an equivalent equilibrium condition consisting of a set of linear inequalities.Based on this,integrating the construction form of prior information for the regulation willingness function,the inverse variational inequalities driven by historical energy consumption data are constructed to achieve the parameterized estimation of regulation willingness for DSFRs in PBDR,and its computational efficiency is analyzed.Additionally,a generalization error evaluation metric for regulation willingness estimation is defined,and its upper bound of generalization error is derived using uncertain convex programming theory.The generalization ability of the proposed parameterized estimation method for regulation willingness is analyzed theoretically.Finally,through case analyses,the accuracy of the proposed parameterized estimation method for regulation willingness is validated,and the role of the accuracy of prior information in the regulation willingness estimation is explored.
