考虑分布式光伏电源与负荷相关性的接入容量分析
Access Capacity Analysis Considering Correlation of Distributed Photovoltaic Power and Load
摘要
Abstract
This paper studies the grid access capacity for distributed photovohaic power,considering the existing distribution network and operation conditions.Firstly,the distribution network and load are analyzed,the initial value of distributed photovoltaic source grid connection location and capacity is set with the historical data,along with the initial correlation matrix constructed.Then,the correlation of distributed photovoltaic power and load is analyzed,a photovoltaic power local consumptive capability index is defined,thus the modified initial correlation matrix can be improved.Based on these analysis,this paper proposes an objective function as the minimum electricity export to the main network,the node voltage and the export power to the grid are the main constraints.The former back flow algorithm and simulated annealing algorithm are used to solve the model.The distribution network of Maxin 10 kV power station is taken as an example.When the correlation of distributed photovoltaic power and load is considered,the simulation results show that grid access capacity for distributed photovoltaic power can be increased effectively.关键词
