Multi-energy park day-ahead economic dispatching method by considering demand response and containing electric vehicles

Abstract

The invention discloses a multi-energy park day-ahead economic dispatching method by considering demand response and containing electric vehicles. The method comprises the following steps: firstly, modeling each device in the park according to the determined specific composition of the multi-energy park; then introducing the electric vehicle while considering the demand response; taking the minimum total operating cost of the park as an objective function; considering related constraint conditions; combining a Monte Carlo scene theory; constructing a multi-energy park day-ahead economic dispatch random model by considering the uncertainty of wind power output and photovoltaic output, verifying the contribution advantages of demand response and electric vehicles to multi-energy park economic operation and new energy consumption, and obtaining a multi-energy park day-ahead economic dispatch strategy containing the electric vehicles and by considering the demand response. A demand response mechanism and an electric vehicle are introduced to further improve the new energy consumption capability of the park and enhance the operation economy of the multi-energy park.

Description

technical field [0001] The invention belongs to the technical field of multi-energy system economic dispatching, in particular to a day-ahead economic dispatching method of a multi-energy park including electric vehicles considering demand response. Background technique [0002] Wind energy is one of the clean and cheap new energy sources with mature development technology, and solar energy is one of the new energy sources with environmental protection and cleanness and great development potential. Both of them are getting more and more attention from researchers, and they are currently the new energy sources with the best development prospects. Research Practice has proved that both can better solve energy and environmental problems. However, wind power and photovoltaic output are greatly disturbed by natural conditions, so there are obvious uncertainties. This uncertainty not only brings a series of safety and stability problems to the grid after new energy is connected to...

Problems solved by technology

In addition, there is currently no mature and extremely effective method for promoting new energy consumption, and there are few studies on the introduction of electric vehicles into the park as a special demand response. Although researchers are gradually increasing the application of demand response to different energy loads, However, the problem of new energy consumption is still not solved
