基于ADMM算法的中低压配电网多目标分布式协调优化运行策略
Multi-Objective Distributed Optimal Scheduling of Distribution Network with High-Permeability Distributed Photovoltaic Resource Access
摘要
Abstract
The access to substantial distributed photovoltaic and energy storage resources on the low-voltage user side is conducive to the local consumption of renewable energy power generation. However,low-voltage users and medium-voltage distribution networks are different stakeholders,and their operation optimization indicators often conflict with each other. Therefore,a multi-objective distributed coordinated optimization operation strategy for medium-and low-voltage distribution networks with high-permeability distributed photovoltaic and energy storage resource access is proposed. Considering the power flow constraints of the medium-and low-voltage distribution networks,an optimization model of the medium-and low-voltage distribution networks is established with the objectives of minimizing the total cost of the distribution network,load rate difference among multiple stations,and energy storage operation cost of the low-voltage distribution network and maximizing the photovoltaic absorption rate. The optimization objectives of the medium-and low-voltage distribution networks are weighted by the entropy weight method. Based on the alternating direction method of multipliers (ADMM),the objective function form of iterative optimization for medium-and low-voltage distribution networks is derived to solve the coordinated optimization model,and a coordinated optimization strategy for medium-and low-voltage distribution networks is designed. The medium-voltage distribution network continuously guides the users of low-voltage distribution networks to adjust the output of distributed power sources through shadow price iterations and realizes the multi-objective coordinated optimization operation of medium-and low-voltage distribution networks through a minimal exchange of boundary information. Finally,the effectiveness and feasibility of the proposed multi-objective distributed optimization operation strategy for medium-and low-voltage distribution networks is verified using the IEEE 33-7 node standard example system.关键词
