摘要
针对开放电力市场环境下存在的多主体利益博弈规划问题,提出一种基于博弈论的"源—网—荷"多主体利益协调互动的主动配电网(ADN)分层规划模型,结合迭代搜索法和改进的粒子群算法来对模型进行求解。模型上层从规划层面上考虑源、网、荷三方各自的决策,以每一个利益主体效益在博弈模式中达到均衡为目标;下层从主动管理层面考虑分布式电源(DG)削减和有载调压变压器(OLTC)调节等策略,以DG年切除量期望值最小为目标。在上层中运用迭代搜索算法搜索多方均衡解,在上层中的每一方主体决策寻优过程以及下层决策寻优过程中运用改进的粒子群算法。通过改进的IEEE 33节点算例,验证所提模型的可行性,为电力市场开放环境下存在多决策主体利益博弈的ADN规划问题提出思路和建议。
Aiming at the problem of multi-agent interest game planning in the open environment of electricity market,a hierarchical planning model is proposed for Active Distribution Network with the coordination and interaction of"source-network-load"multi agents based on the game theory,and the iterative search method and improved particle swarm optimization algorithm is applied to get the solution.The upper layer of the model considers the respective decisions of the source,network and load agents,and aims at achieving the equilibrium in the game mode for each interest body.The lower layer considers the DG(Distributed generation)reduction and OLTC(On-load Tap Changer)adjustment strategies from the active management level.The target of the lower layer is minimizing the expected value of annual load cutting of DG.In the upper layer,the iterative search algorithm is utilized to search the equilibrium solution of multi-agents,and the improved particle swarm optimization algorithm is employed in the optimization process of each agent in the upper layer and the optimization process in the lower layer.Finally,an improved IEEE 33-node example is simulated to verify the feasibility of the model.It also gives ideas and suggestions for the ADN planning game problem with multi-decisions in the open environment of electricity market.
