Abstract

This paper addresses a computational issue of solving stochastic economic dispatch with the participation of uncertain demand response providers. In particular, we study the linear constraints in the chance constrained formulation of the dispatch problem. A semi-analytical method is proposed to simplify the formulation and computation of chance constraints in the economic dispatch problem. Compared with existing methods such as deterministic, analytical method and sample-based approaches, the advantage of the semi-analytical method lies in its lower computational cost, controllable level of risk and low information exchange between agents and the independent system operator. Numerical results on the IEEE 14 bus system with two demand response providers illustrate the potential efficacy of the proposed method.
有需求响应提供者的机会约束随机经济调度的半解析方法
本文研究了不确定需求响应提供者参与下求解随机经济调度的计算问题。特别地,我们研究了调度问题的机会约束公式中的线性约束。为了简化经济调度问题中机会约束的表述和计算,提出了一种半解析方法。与现有的确定性方法、解析方法和基于样本的方法相比,半解析方法的优势在于计算成本低、风险可控、agent与独立系统操作者之间的信息交换少。在具有两个需求响应提供者的IEEE 14总线系统上的数值结果表明了所提方法的潜在有效性。
