Abstract

The invention discloses a multi-objective planning method for an integrated energy system, comprising: constructing a multi-objective planning model of an integrated energy system including optimization objectives and operation constraints based on a practical interval-based safety domain; solving the above-mentioned planning model by using an NSGA-II algorithm to obtain a A set of optimal system planning solutions; for each set of planning solutions, by reconfiguring key elements of the system to increase its capacity, a more balanced and less uncertain impact of renewable energy can be obtained at minimal economic cost. This method helps to improve the security state of the system and expand the area where the system can absolutely operate safely.

Description

technical field [0001] The invention relates to the field of comprehensive energy systems, the field of security analysis of regional comprehensive energy systems including renewable energy, and in particular to a multi-objective planning method for comprehensive energy systems based on practical interval security domain theory. Background technique [0002] Due to the aggravation of the energy crisis and the more serious environmental pollution caused by the extensive use of fossil energy, there is an urgent need to build an efficient, clean and sustainable energy system worldwide. Renewable energy power generation such as wind power and photovoltaics, as one of the representatives of green power generation, has the characteristics of low carbon, environmental protection and sustainability. Therefore, a comprehensive energy system integrating renewable energy is rapidly developing and widely used. It can rationally utilize renewable energy and improve its absorption capacit...
