Embodiment Construction

[0067] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0068] Since the photovoltaic power generation and the traditional power grid have certain complementary coordination characteristics in time and space, and the large-scale electric vehicle charging station has good regulation performance, it can effectively stabilize the photovoltaic power generated when it is connected to the power system. volatility. Photovoltaic power stations, electric vehicle charging stations, and traditional user loads form a regional energy system, forming a complementary power generation system for photovoltaic vehicles and electric vehicles, and by formulat...

Abstract

The present invention relates to a collaborative interaction method and system between an electric vehicle charging station and a photovoltaic power station. The method includes: obtaining node power information of each photovoltaic power station, a user's power terminal, and an electric vehicle connected to the electric vehicle charging station in the area; According to the obtained information, an electric vehicle-photovoltaic power generation collaborative interaction dynamic programming model is established, and the electric vehicle-photovoltaic power generation collaborative interaction dynamic programming model includes the objective function and corresponding constraint conditions to realize the minimum variance of the energy system load in the region; The particle swarm optimization algorithm is used to solve the dynamic programming model of electric vehicle-photovoltaic power generation collaborative interaction; according to the obtained optimal solution, the energy collaborative interaction strategy in the regional energy system is formulated. Compared with the prior art, the present invention realizes the energy synergistic interaction between the photovoltaic power station and the electric vehicle charging station, ensures the stable operation of the regional energy system, and simultaneously takes environmental protection into consideration.

Description

technical field [0001] The invention relates to the field of coordinated control of regional energy sources, in particular to a method and system for collaborative interaction between an electric vehicle charging station and a photovoltaic power station. Background technique [0002] Ensuring the security of energy use and dealing with greenhouse gas emissions and pollution mainly caused by the extensive use of fossil energy has become the core goal of the energy development strategies of major countries in the world. At present, to promote the transformation of the energy system to a clean and low-carbon direction, how to solve the randomness and uncertainty brought by the access of renewable energy to the load of the traditional grid, and how to effectively stabilize the load fluctuation have become problems that need to be solved now. [0003] At the same time, electric vehicles are gradually being used in modern society on a large scale. The large-scale development of el...
