In the method provided by the invention, the first layer adopts theproposed expandable global quadratic heuristic programming algorithm to distribute the output of the traditional generator set and distribute the output sum of other comprehensive energy sources. Andthe second layer adopts a proposed fast contraction scheduling optimization algorithm to solve various comprehensive energy output optimal combinations. And the third layer adopts a proposed micro-granularity real-time control algorithm to regulate and control various distributed energy sources, flexible loads and energy storage equipment. According to the three-layer linkage mechanism method, each layer of regulation and control executes a flexible energy distribution strategy according to the real-time information of the respective region and the previous layer, and the problem of comprehensive energy flexible cooperative control is solved.

Description

technical field [0001] The invention belongs to the field of optimal scheduling and control of integrated energy systems, and relates to a real-time scheduling and control method for interactive integrated energy systems, which is suitable for power generation scheduling and frequency control of integrated energy. Background technique [0002] With the rapid growth of distributed energy grid-connected installed capacity, the energy structure of the power system has undergone great changes. A large amount of energy with random properties brings challenges to power system power frequency stability regulation, safe operation and economic dispatch. However, the traditional highly centralized unified management and dispatch mode does not support the complementary transformation of multiple energy sources, which makes the utilization rate of distributed new energy grid connection low, and fails to interact well with end power users. Therefore, it is necessary to optimize the ener...

Problems solved by technology

In the past, the comprehensive energy scheduling control method of comprehensive energy did not consider the hierarchical control of the system, and treated the system as a centralized scheduling process; or did not refine the comprehensive energy system to the third level, and the energy types were not fully considered; the third level of energy The scheduling time scale is single, etc.

This type of method lacks close cooperation between energy sources, resulting in insufficient energy utilization

[0014] If the system is not hierarchically treated as a centralized scheduling process, a large number of state variables will make the calculation difficult to converge, and it is easy to fall into the disaster of dimensionality and cannot be solved.
