Abstract

The invention relates to a PSO-based optical storage, charging and conversion integrated charging station collaborative optimization scheduling method and device. The method comprises the following steps of obtaining measurement point information of each photovoltaic power generation module, each energy storage module and each electric vehicle charging and conversion module in an optical storage,charging and conversion integrated charging station; establishing a co-scheduling strategy model according to the obtained information, wherein the co-scheduling strategy model comprises an objectivefunction and constraint conditions for realizing the minimum operation cost of the light storage, charging and conversion integrated charging station; solving the collaborative scheduling strategy model through a particle swarm algorithm; and making a power grid power input and energy storage output plan of the optical storage, charging and conversion integrated charging station according to the obtained optimal solution. Compared with the prior art, the output of each module is cooperatively optimized and dispatched according to the cooperative control characteristic of each module in the charging station during operation, so that the influence of the integrated charging station on the stability of a power grid system is effectively reduced, and meanwhile, the safe and stable operation ofthe integrated charging station is also ensured.

Description

technical field [0001] The invention relates to the field of power grid dispatching, in particular to a PSO-based method and device for coordinated optimal dispatching of a charging station with integrated optical-storage charging and swapping. Background technique [0002] Today, the global environment is getting worse and worse, and the problem of energy shortage is becoming more and more serious. All countries have to develop towards the common goal of efficient, clean and renewable energy transformation. In recent years, with the rapid development of new energy power generation, energy storage and other technologies, electric vehicles with electric energy as the main power have been rapidly developed and popularized in big cities due to their unique advantages and conditions. [0003] The charging station for electric vehicles not only has a positive impact on the ecological environment, it can also be used as a high-power energy storage and load to achieve load balancin...

AI Technical Summary

Problems solved by technology

First, a large number of electric vehicle charging stations connected to the grid will lead to an increase in grid load, a greater difference in grid load peaks and valleys, and require higher installed capacity

Secondly, the charging behavior of electric vehicles has great uncertainty and randomness. The disorderly charging and swapping of electric vehicle users will also have a negative impact on the safe and stable operation of the power grid, including the aggravation of the load peak-valley difference on the distribution network, Negative effects such as line overload, which will increase the difficulty of grid control and reduce the reliability of the entire power system
