Assessment method of 10KV planning power grid distributed photovoltaic consumption capacity

Abstract

The invention discloses an assessment method of 10KV planning power grid distributed photovoltaic consumption capacity. The assessment method comprises the following steps: establishing a 10KV planning power grid distributed photovoltaic consumption capacity assessment model; determining power distribution safety standard and power grid parameter computation method after the distributed photovoltaic accesses to a power grid; developing regional distributed photovoltaic resource total assessment, and predicting planning year distributed photovoltaic development level; determining the planning year power grid structure and a running way, determining a power grid load location, capacity size and the distributed photovoltaic location and size information; modeling in the system to analyze thepower grid flow; analyzing the 10KV planning power grid distributed photovoltaic consumption capacity under different scene modes; and customizing the measure in a targeted way according to an analysis result, and improving the power grid consumption level. Through the method disclosed by the invention, the current situation and the consumption capacity of the planning power grid distributed photovoltaic can be effectively analyzed, an access problem to the distributed power supply by the conventional power grid is solved, and the coordinated development of the power grid and the distributed photovoltaic is promoted.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to a method for evaluating the distributed photovoltaic accommodation capacity of a 10 kV planned power grid. Background technique [0002] With the continuous decline of environmental quality worldwide and the depletion of traditional fossil fuel resources, people are increasingly advocating the concept of green and environmentally friendly life. As a typical clean and renewable energy, photovoltaics has developed rapidly in recent years due to its rich resources and wide application range. In 2017, photovoltaic installed capacity has surpassed coal power and nuclear power, and has become the world's largest new power installed capacity. With a large number of distributed photovoltaics connected to the 10 kV distribution network, the intermittent and fluctuating characteristics of its power generation have brought great challenges to the operation of the distribution n...
