Abstract

The invention provides a method and system for optimizing operation of a new energy combined cooling heating and power system according to time scales, and the method comprises the steps: carrying out the time scale decomposition of a system based on an operation optimization model of the new energy combined cooling heating and power supply system, and dividing the system into a quick-change subsystem and a slow-change subsystem according to the difference of a state variable in a time scale; for the decomposed fast-varying subsystem and slow-varying subsystem, continuously updating the source and load input information of the system, carrying out rolling operation optimization on electricity and cold/heat energy in different time scales, and adjusting the real-time output of cold/heat supply equipment. Therefore, collaborative optimization of the electric energy and the cold/heat energy on different time scales is realized, and the requirements of the actual operation condition of the system can be better met.

Description

technical field [0001] The disclosure belongs to the field of energy technology, and in particular relates to a time-scale operation optimization method and system for a new energy combined cooling, heating and power supply system. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] As one of the main forms of distributed energy supply, combined cooling, heating and power (CCHP) system can realize the effective unification of high-grade electric energy and low-grade heating and cooling energy demands. Improve the comprehensive utilization efficiency of energy. Vigorously developing the CCHP system with energy saving and environmental protection advantages has become an effective way to improve the energy structure and promote sustainable development in our country. In recent years, with the improvement of the technical level of renewable en...
