Renewable energy capacity allocation method for promoting the consumption of the renewable energy

Abstract

The invention discloses a renewable energy capacity allocation method for promoting consumption, includes the following steps: (1) acquiring a power network topology and modeling according to the power network structure to form a data matrix capable of representing the characteristics of the power network, (2) to test the rationality of power network data and its adaptability to power network planning, (3) Analyzing the boundary conditions of various flexible resources in the power grid, (4) uploading the renewable energy and load power curve in the dispatching center, (5) establishing the renewable energy planning model which includes the planning layer model and the operation layer model, (6) solving the renewable energy planning model based on Matlab simulation platform; The invention comprehensively considers the constraint of source-network-load-storage, and establishes a model aiming at the renewable energy consumption based on the objective functions and constraint conditions ofthe planning layer and the operation layer, so as to obtain the multi-point layout and planning of the renewable energy with the highest renewable energy utilization rate and the largest renewable energy consumption capacity.

Description

technical field [0001] The invention relates to a capacity allocation method for promoting the consumption of renewable energy, which maximizes the utilization efficiency of renewable energy with minimum economic investment, and belongs to the technical field of energy management. Background technique [0002] In recent years, the fossil energy crisis and harsh environmental changes have prompted countries around the world to transform their energy structures. Renewable energy sources (RES), represented by wind power and photovoltaics, have the advantages of low operating costs, less environmental pollution, and abundant reserves, and have been widely recognized around the world. The European Union proposes to achieve the development goals of reducing carbon dioxide emissions by 20% compared with 1990, using renewable energy to 20% of total energy consumption, and reducing total energy consumption by 20% by 2020. In 2016, my country's Energy Administration issued the Chines...

Problems solved by technology

Moreover, existing renewable energy planning methods have deficiencies, such as stochastic programming theory that fails to fully consider the spatio-temporal characteristics of renewable energy power generation

Blind planning of renewable energy without considering the constraints of power reduction rate cannot solve the problem of renewable energy consumption quota indicators

[0009] 5. Separation of grid planning and operation

Obviously, the indicators of renewable energy consumption capacity are not perfect, the limited output of wind power and photovoltaic units leads to low utilization of grid assets, and the inconsistency between renewable energy planning and the actual consumption capacity of the grid leads to the return on investment of renewable energy. The problem of low rate is urgent to be solved in this field
