Abstract

The invention discloses an operation method of a combined heat and power system containing wind and light renewable energy. The method includes the following steps that: the optimization objective andconstraint function of the system containing the wind and light renewable energy are set, and an optimization model is established; a Monte Carlo random sampling-based multi-objective optimization algorithm is adopted to solve the optimization model, and a plurality of Pareto optimal solutions can be obtained; and decision maker preference information is set, and one of the Pareto optimal solutions is selected as the operation plan of the combined heat and power system. According to the method of the present invention, the multi-objective optimization algorithm is adopted to optimize the combined heat and power system with factors such as heat and power load and the uncertainty of renewable energy power generation considered, and therefore, the method accords with actual conditions, and is more feasible; the evolutionary multi-objective optimization algorithm is adopted to obtain a set of Pareto optimal solutions which have their respective advantages, a decision maker can select andimplement the operation plan of the combined heat and power system according to different situations. The method of the invention is used for calculating the optimal operation plan of the combined heat and power system.

Description

technical field [0001] The invention relates to the technical field of an operation method of a combined heat and power system including wind and solar renewable energy. Background technique [0002] Energy, development and environmental issues are intertwined and become the bottleneck restricting my country's modernization drive. In order to improve energy utilization rate, realize energy saving and environmental protection, the Combined Heat and Power (CHP) system based on the concept of energy cascade utilization has gradually become an energy utilization method that countries are striving to develop. [0003] The CHP system can consider the supply of heat load and electric load at the same time, use the waste heat generated in the power generation process to store heating, can effectively realize the cascade utilization of energy, and greatly improve the utilization rate of energy. The core of the optimal economic operation of the CHP system is how to formulate the oper...
