Problems solved by technology

In the existing technology, the total load is mainly determined based on load forecasting, and then the load is distributed to each substation according to the principles of capacity-load ratio. However, there is no unified principle and idea for how to distribute the load, and most of them are artificially based on load forecasting. Allocation adjustment is blind, and at the same time, the efficiency is not high, and it is impossible to realize fast calculation with the help of a computer, and the adaptability is poor

Abstract

A load distribution algorithm of a substation belongs to that technical field of electric power distribution. A power supply area divide unit is included, a load prediction unit is connected to the power supply area division unit through data, a power supply proportion estimation unit is connected to the data of the power supply proportion estimation unit, an association matrix unit is connected to the data of the association matrix unit, and a load distribution calculation unit is connected to the data of the association matrix unit. The methd specifically comprising the following steps of: 1) counting the power supply area belonging to each substation; 2) forecasting the load from each power supply area to the planning level year; 3) estimating the proportion of power supply in the planning level year; 4) forming an association matrix according to the power supply proportion; 5) calculating the load distribution, which solves the problem of blindness, poor adaptability and low efficiency of the existing substation load distribution, and directly forms the load distribution coefficient matrix of the substation through the system network equation, thereby effectively establishing an analytical model, and greatly improve the accuracy, adaptability and efficiency of the load distribution process.

Description

technical field [0001] The invention relates to a substation load distribution algorithm, which belongs to the technical field of electric power distribution. Background technique [0002] In recent years, in order to ensure the rationality and fairness of the market-oriented operation mechanism of the electric power industry, it is necessary to clarify the load distribution work in the simulation verification of power grid planning. In the existing technology, the total load is mainly determined based on load forecasting, and then the load is distributed to each substation according to the principles of capacity-load ratio. However, there is no unified principle and idea for how to distribute the load, and most of them are artificially based on load forecasting. Allocation adjustment has a large blindness, and at the same time, the efficiency is not high, and it is impossible to realize fast calculation with the help of a computer, and the adaptability is poor. [0003] Ai...
