Method for determining optimal photovoltaic configuration capacity of distribution network node

Abstract

The invention relates to a method for determining the optimal photovoltaic configuration capacity of a distribution network node. The method comprises the following steps: establishing an evaluation model of the maximum photovoltaic output allowed to be injected at each time of a year by the distribution network node and adopting the annual time series power flow simulation of a genetic algorithmto solve the model so as to obtain the maximum photovoltaic output allowed to be injected at each time of a year by the distribution network node; and establishing a full life cycle income evaluationmodel of a photovoltaic power station considering light abandonment based on the results and using the genetic algorithm to solve the model so as to obtain the optimal photovoltaic capacity maximizingthe income of the power station. If the capacity is higher than the maximum access capacity, the safe operation of the distribution network is ensured through light abandonment. Compared with the methods in the prior art, the method has the advantages of rapidity, reliability and the like.

Description

technical field [0001] The invention relates to a method for configuring photovoltaic capacity in a distribution network, in particular to a method for determining the optimal configuration capacity of photovoltaic nodes in a distribution network. Background technique [0002] With the global shortage of fossil energy and the escalation of environmental pollution problems, coupled with the support of policies related to renewable energy power generation, renewable energy power generation has received widespread attention. Among them, photovoltaic power generation is less restricted by geographical and resource conditions. The power generation process is noise-free and pollution-free, and installation and maintenance are simple. It has become one of the research and application hotspots in various countries. Due to the randomness and intermittent nature of photovoltaic output, the large-scale access of photovoltaics will adversely affect the operation safety of the distributi...
