Distributed photovoltaic power generation management and settlement method based on electric power spot environment

Abstract

The invention relates to a distributed photovoltaic power generation management and settlement method based on an electric power spot environment, and the method is used for the execution of dispatching equipment assisting the power dispatching of a power grid in the electric power spot environment, and comprises the steps: building a power dispatching function of the power grid according to the power dispatching parameters of the power grid and the power generation information of a photovoltaic power generation system; solving the power dispatching function to obtain an electric quantity dispatching optimal solution of the photovoltaic power generation system; and acquiring an electric quantity dispatching optimal scheme of the power grid according to the electric quantity dispatching optimal solution, sending the electric quantity dispatching optimal solution to a dispatching control system, and performing dispatching control on power generation and energy storage work of the photovoltaic power generation system and electric quantity clearing work of a clearing system of the power grid by the dispatching control system according to the electric quantity dispatching optimal scheme. According to the invention, the electric quantity of the distributed photovoltaic power generation system can be accurately scheduled and stored, and the lacked electric quantity can be dispatchingfrom the power grid when the power generation quantity and the energy storage quantity of the photovoltaic power generation system are less than the demand quantity, so that the actual application demand is met.

Description

technical field [0001] The present application relates to the technical field of distributed photovoltaic power generation, in particular to a management and settlement method for distributed photovoltaic power generation based on a power spot environment. Background technique [0002] The power system is a power production and consumption system composed of power generation, power transmission, power transformation, power distribution and power consumption. Its function is to convert the primary energy in nature into electric energy through the power generation device, and then supply the electric energy to various users through power transmission, transformation and distribution. The whole composed of substations of various voltages and transmission and distribution lines in the power system is called the power grid. [0003] With the continuous development of the economy and industry, the consumption of electricity is increasing, and the transmission and distribution ele...
