Embodiment

[0128] The present invention provides an optimal operation method of cogeneration microgrid system considering demand response, such as Figure 17 shown, including the following steps:

[0129] Step 1. Construct the cogeneration microgrid system of the solar thermal power station

[0130] The structure of the microgrid system for cogeneration of solar thermal power station is as follows: figure 1 As shown, including wind energy, solar energy, electric energy and thermal energy. The electric energy in the microgrid is mainly provided by photothermal power stations, wind power stations and electric energy storage devices, and electric energy can also be purchased and sold in the electricity wholesale market. The thermal energy in the microgrid is provided by the heat pump and the heat storage device in the photothermal power station. The loads in the microgrid include electrical loads and thermal loads, and the two loads are divided into inelastic loads and elastic loads that...

Abstract

The invention discloses an optimized operation method for a heat and power cogeneration micro grid system of a solar thermal power station. According to the technical scheme adopted by the invention,the method comprises the following steps: firstly proposing the solar thermal power station introduced into the heat and power cogeneration micro grid system to assist system operation, and constructing a new micro grid system architecture by combining energy conversion equipment such as a wind power station, an electric energy storage device and a heat pump; then taking a retail electricity priceand a retail heat price as signals and guiding users in the micro grid system to participate in demand response, and building a demand response model for an electrical load and a heat load based on aprice elasticity matrix; on the basis, considering uncertainty of wind power and solar power outputs, and building a fuzzy chance constrained planning model by taking maximization of running benefitof a micro grid as a goal; and then simplifying the model, finally forming a mixed integer linear programming problem, and solving by adopting an efficient commercial solver CPLEX. The method disclosed by the invention considers the uncertainty of the wind power and solar power outputs and maximizes the running benefit of the micro grid system.

Description

technical field [0001] The invention relates to the field of cogeneration microgrid systems of photothermal power stations, in particular to an optimized operation method for cogeneration microgrid systems of photothermal power stations considering demand response. Background technique [0002] Intermittent renewable energy generation such as wind power and solar energy consumption and multi-energy conversion technology has gradually become a research hotspot in the field of power systems. China's direct solar energy resources are mainly concentrated in the west and north, and these places also have abundant wind energy resources and high heat load demand. The output of wind power and photovoltaics is intermittent and uncertain, which will affect the safety and economy of power system operation after being connected to the grid. The microgrid solves the problem of distributed wind power and photovoltaics to a certain extent. The microgrid can organically integrate a variety...
