Optimal operation strategy and load characteristic modeling method of park-type integrated energy system

Abstract

The invention proposes an optimal operation strategy and a load characteristic modeling method for a park-type comprehensive energy system. The method includes establishing the system revenue of each time section with the maximum operating benefit as the objective function according to the electricity sales revenue and the total cost of power generation of the park-type comprehensive energy system. model; establish the constraints of the park-type integrated energy system; under the constraints of the park-type integrated energy system, take the maximum benefit from the operation of the park-type integrated energy system as the objective function, formulate the power output strategy of the park-type integrated energy system. The invention comprehensively considers various market factors such as time-of-use electricity price, energy storage charging and discharging cost, photovoltaic grid-connected benchmark electricity price, and aims to maximize the operating profit of the comprehensive energy system of the commercial park, comprehensively considers market factors and operating economy, and proposes a grid-connected load. Characteristic modeling method, and a variety of optimal operation strategies can be obtained, which can realize the investment and return value-added of the park-type integrated energy system.

Description

technical field [0001] The invention belongs to the technical field of integrated energy systems, and particularly relates to an optimized operation strategy and a load characteristic modeling method of a park-type integrated energy system. Background technique [0002] Under 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. There are various types of distributed energy sources in the integrated energy system, including uncontrollable power sources such as photovoltaic cells and wind turbines, 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 outputs and their impact on the distribution network are related to whether the integrated energy system can be successfully integrated into the existing power grid to operate safely ...
