Regional integrated energy system operation optimization method

Abstract

The invention discloses a regional integrated energy system operation optimization method, which is applied to the technical field of new energy resources and microgrids. The regional integrated energy system operation optimization method comprises the steps of: firstly, establishing a regional integrated energy system operation optimization model of an objective function taking a maximum wind power consumption amount as an optimization object and taking a minimum operation cost of a regional integrated energy system as an optimization object; and secondly, restricting cold and thermoelectricload of the model, equipment operation, electric energy storage system and transferable load, and solving the objective function under the existing constraint conditions. The regional integrated energy system operation optimization method can exchange a small amount of load transfer cost for lower integrated energy system operation cost and higher wind power consumption capacity, and improves theoperating conditions of a controllable unit in the system.

Description

technical field [0001] The invention relates to the technical field of new energy and micro-grid, and more specifically, to a method for optimizing the operation of a regional comprehensive energy system. Background technique [0002] The operation optimization of the integrated energy system refers to the optimization of the output of each distributed power source in the system with the goal of maximizing social benefits by comprehensively considering the operation constraints of the equipment in the system and the system operation constraints. Researchers from various countries have carried out different levels of analysis and research on improving wind power consumption capacity and system economic operation, and have made some progress. For example, the energy storage system is used to improve the system's wind power consumption capacity and operation control capability, and a micro-grid multi-objective operation optimization model considering interruptible loads is esta...

Problems solved by technology

[0003] However, most of the previous studies on the optimal operation of integrated energy systems have not considered how the system can improve the consumption of wind power. However, in the actual operation of integrated energy systems, it is often necessary to evaluate the amount of wind power consumption to optimize the operation of the system. If the consumption of wind power is not considered, there will be a large deviation between the theoretical research results of operation optimization and the actual operation results, making the operation optimization results unreliable
