Electric energy optimal distribution method and system for distributed power supply grid connection

Abstract

The invention discloses an electric energy optimal distribution method and system for grid connection of a distributed power supply. The method comprises the following steps: compiling an identity code for a distributed power supply module; obtaining a target node detection signal, a target load detection signal and an adjacent point detection signal; inputting the target node detection signal, the target load detection signal and the adjacent point detection signal into an electric energy optimal configuration model corresponding to the identity code, and outputting optimal configuration parameters by combining the electric energy optimal configuration model with the working condition of the power distribution network; and feeding back the optimal configuration parameters to a unit sub-controller, and controlling the target distributed power supply module for industrial control by the unit sub-controller. According to the invention, electric energy resource optimal configuration of the power distribution network with a plurality of distributed power supplies can be realized, and the states of the adjacent distributed power supplies are coordinated and adjusted, so that each distributed power supply provides the optimal electric energy ratio for the power grid, the supply states of the distributed power supplies are adjusted according to the actual operation state of the powergrid, and stable, safe and reliable operation of the power grid of the distributed power supplies can be ensured.

AI Technical Summary

Problems solved by technology

However, this method cannot optimally distribute the electric energy generated by the distributed power generation to the distribution network, and the optimal allocation of resources in the power grid is poor.

Direct switching in and out of distributed power generation will inevitably cause fluctuations in the grid, affect the operation of the grid itself and other integrated distributed power sources, and even cause failure or damage

Moreover, it is impossible to combine the mutual influence of multiple distributed power sources in the power grid, and it is impossible to make each distributed power source provide the optimal power ratio for the power grid, so that the entire distribution network with multiple distributed power sources connected to the grid cannot be stabilized. , safe and reliable operation
