Abstract

The invention relates to a multivariate regulation and control method for a power grid. According to the invention, the system repeatedly learns historical data in the same time period of the previousday for a period of time and performs multiple iterations so as to continuously adjust a regulation and control coefficient of the system and determine an output value required by a node of each power generation unit of the power grid; then the outputs required by all nodes in the power grid are added to obtain the planned output condition of each power generation unit of the power grid in the time period of the subsequent day; then the steps are repeated in the next time period, finally the output of each power generation unit of the power grid in all time periods of the whole day is finallyadjusted so as to enable the day-ahead plan to be more accurate. Real-time regulation and control can be performed through AGC for generated errors so as to ensure the frequency of the power grid tobe stable.

Description

technical field

[0001] The invention belongs to the technical field of smart grids, and in particular relates to a multi-element grid coordination control method based on multi-model neural network self-adaptive regulation. Background technique

[0002] In recent years, a new round of energy transformation is advancing globally. The structural adjustment of my country's energy industry is accelerating. The grid-connected capacity of clean energy represented by photovoltaics and wind power is increasing. The utilization of energy is gradually becoming characterized by high efficiency, diversification and intelligence. , requiring accelerated improvement of the power grid to adapt to the optimal allocation of energy across the country. Facing the pressure of global environmental degradation and resource shortage, energy conservation, emission reduction and improvement of energy utilization efficiency have become the requirements that the future power grid must meet. At present...
