Description

technical field [0001] The invention belongs to the technical field of urban regional comprehensive energy system planning and optimization, and in particular relates to a regional comprehensive energy system energy storage optimization configuration method based on operational benefit increment. Background technique [0002] The anti-peak-shaving characteristics of wind power and the "heat-fixed power" mode in the heating season will lead to serious wind curtailment, resulting in energy waste. With the advancement of the Energy Internet, the development of integrated energy systems and the emergence of various energy storage methods, the utilization rate of renewable new energy can be improved by establishing the operation mode of regional integrated energy systems with multiple energy storage methods. [0003] Because the regional integrated energy system is affected by the randomness, intermittency, and uncertainty of the renewable energy in the system, and the system usu...

Problems solved by technology

At present, there are certain studies on the optimal dispatching model and control method of the regional integrated energy system with energy storage equipment at home and abroad, but most of them only study the economy and reliability of a single energy storage device for the regional integrated energy system to absorb new energy. However, there are few literatures on the impact of multiple energy storage devices such as electricity, heat, cooling, and gas on the economy and reliability of the regional comprehensive energy system, and the issue of the priority of energy storage equipment allocation.

On the one hand, the existing research considers that the energy storage equipment in the regional integrated energy system is not comprehensive; on the other hand, the target factors considered in the optimization process are not comprehensive, so the optimization results have large errors; finally, under the conditions of the existence of multiple energy storage methods However, none of them have clearly given the energy storage methods suitable for allocation in the researched regional integrated energy system.
