摘要
为应对分布式光伏大规模接入配电网造成的净负荷波动问题,提出一种考虑需求响应的储能双层规划方法。首先,分析配电网在不同光伏渗透率下的灵活性需求以及各类灵活性资源的运行特性。其次,通过主成分分析法和分层聚类算法得到典型光—荷场景。然后,建立考虑需求响应的配电网储能双层规划模型,其中上层规划层以综合成本最小为目标优化储能的规划方案;下层运行层以运行成本最小为优化目标,考虑储能、价格型需求响应以及可中断负荷等可调控对象,制定各典型场景下的配电网运行策略。同时,为有效求解双层规划模型,采用上下层关联统一的方法将双层模型转换为单层模型,再通过调用Gurobi求解器进行求解。最后,基于IEEE33节点系统对配电网不同光伏渗透率条件下进行算例分析,验证所提方法的有效性。
In order to deal with the problem of net load fluctuation due to access of large⁃scale distributed PV to the distribution network,a kind of bi⁃level energy storage planning method considering demand response is proposed.Firstly,the flexibility requirements of distribution network under different photovoltaic permeability and the opera⁃tion characteristics of various flexibility resources are analyzed.Then,the typical scenarios of distributed photovolta⁃ic and load are obtained by principal component analysis method and hierarchical clustering algorithm.After that,a bi⁃level planning model for distribution network energy storage considering demand response is set up.The upper planning layer optimizes the energy storage planning scheme with the goal of minimizing the comprehensive cost.The lower operating layer minimizes the operating cost target,and considers the controllable objects such as energy stor⁃age,price⁃based demand response and interruptible load to solve the operation strategy of each typical scenarios.At the same time,for effectively solving the bi⁃level planning model,the double⁃layer model is converted into a single⁃layer model by using the approach of upper and lower level correlation and solved by Gurobi solver.Finally,the IEEE33 node system is used to analyze the different photovoltaic permeability of the distribution network and the ef⁃fectiveness of the proposed method is verified.
