Park-type comprehensive energy system optimization operation strategy and load characteristic modeling method

Abstract

The invention provides a park-type comprehensive energy system optimization operation strategy and load characteristic modeling method, and the method comprises the steps: building a system income model of each time section according to the electricity selling income of a park-type comprehensive energy system and the total cost of power generation and by taking the maximum operation benefit as anobjective function; establishing constraint conditions of the park-type comprehensive energy system; and under the constraint conditions of the park-type comprehensive energy system, with the maximumoperation benefit of the park-type comprehensive energy system being taken as the objective function, making a power output strategy of the park-type comprehensive energy system. According to the invention, multiple market factors such as time-of-use electricity price, energy storage and charging and discharging cost and photovoltaic on-grid benchmarking electricity price are comprehensively considered, the maximum operation income of the commercial park comprehensive energy system is taken as a target, the market factors and operation economy are comprehensively considered, a grid-connected load characteristic modeling method is proposed, multiple optimized operation strategies are obtained, and investment and return appreciation of the park-type comprehensive energy system can be realized.

Description

technical field [0001] The invention belongs to the technical field of comprehensive energy systems, and in particular relates to an optimal operation strategy and a load characteristic modeling method of a park-type comprehensive energy system. Background technique [0002] Against the background of increasingly tight environmental pollution and energy crisis, the park-type integrated energy system has been greatly developed as a collection of clean energy. At the same time, the market-oriented reform on the electricity sales side will further promote the development of the integrated energy system. There are various types of distributed energy in the integrated energy system, including not only uncontrollable power sources such as photovoltaic cells and wind turbines, but also controllable power sources such as fuel cells and micro gas turbines, as well as various energy storage devices and new loads. How to evaluate The characteristics of these power sources and their imp...
