Embodiment

[0038] This embodiment proposes a collaborative planning method that considers the orderly access of distributed photovoltaics to the power grid. figure 1 , including the following steps:

[0039] S1. Predict the installed capacity of distributed photovoltaics in the planning area to obtain the total installed area of ​​photovoltaics; including the following steps:

[0040] Obtain the total electricity consumption, maximum load and distributed photovoltaic installed capacity in the planning area over the years, use the quadratic exponential smoothing method to predict the distributed photovoltaic installed capacity in the planned year, and obtain the total photovoltaic installed area according to the distributed photovoltaic installed capacity in the planned year.

[0041] The basic formula of quadratic exponential smoothing:

[0042] St=αSt+(1-α)St-1;

[0043] Yt+T=at+btT;

[0044] at=2St-St;

[0045] bt=(α / 1-α)(St-St);

[0046] Among them: St is the exponential smoothin...

Abstract

The invention provides a collaborative planning method considering distributed photovoltaic ordered access to a power grid, and the method comprises the following steps: predicting the distributed photovoltaic installation capacity in a planning region, and obtaining a total photovoltaic installation area; setting a plurality of to-be-installed areas in the planning area, and setting the maximum photovoltaic installation area of the pre-installation area; selecting a plurality of transformer substations in the planning area as to-be-connected transformer substations, and obtaining a cable path from each to-be-connected transformer substation to each to-be-installed area; and constructing a transformation cost function as a target function, solving an optimal solution of the transformation cost function, and obtaining the area and area of distributed photovoltaic installation. According to the method, the optimal cost is taken as a target, and the distributed photovoltaic devices are installed in a delimited area of a large city, so that the distributed photovoltaic devices are orderly connected to a power grid.

Description

technical field [0001] The invention relates to the technical field of distributed photovoltaics, in particular to a collaborative planning method considering the orderly access of distributed photovoltaics to a power grid. Background technique [0002] As a typical clean and renewable resource, distributed photovoltaic has developed rapidly in recent years due to its rich resources and wide application range. It has become an inevitable trend to integrate the access and consumption of distributed photovoltaic into urban distribution network planning. The current research mainly optimizes capacity and site selection by establishing a planning model, with the goal of maximizing the access capacity, and solves the maximum access capacity of distributed power sources in the distribution network through genetic algorithms; The maximum allowable output power of distributed photovoltaic power sources under all load levels and relevant observation data are used to obtain the peak ...
