Embodiment

[0225] A. Analysis of load and photovoltaic power generation in the new area:

[0226] The new district of XX City plans to use 1.5 square kilometers as a photovoltaic power generation demonstration area, with a maximum load of 12.89MW. Arrange photovoltaic panels on the roof of each building, and build the entire residential community into a building-integrated grid-connected photovoltaic power generation project. The construction projects are mainly fund-raising and unified construction of affordable housing, with a total of 294 buildings; infrastructure facilities such as municipal and schools, with a total of 34 buildings; and public service facilities such as supermarkets, with a total of 11 buildings.

[0227] The total annual radiation of the new area is about 1500kWh / ㎡, and the annual sunshine hours are above 2800h. The solar energy resources belong to the category II "very rich zone". The installed capacity of solar energy is 13.4MW, the annual power generation is 13...

Abstract

The invention relates to a cost benefit analysis method of a renewable energy source distributed generation operation mode. The method comprises the following steps: determining all operation modes of the renewable energy source distributed generation; performing match analysis on the distributed contribution and a load curve, and determining different types of electric quantity; determining property right demarcation points, boundary conditions and calculation parameters of the distributed generation under different operation modes; determining the expense composition and income composition of the distributed generation in the whole life cycle under different operation modes; determining the total expense present value, annual average expense present value, total income present value and annual average income present value of the distributed generation in the whole life cycle under different operation modes; determining the benefit/cost value PI of the distributed generation in the whole life cycle under different operation modes; and selecting the scheme with the greatest benefit/cost value, and determining the optimal operation mode of the distributed generation. The method provided by the invention lays a firm theoretical foundation for making supporting policies for the renewable energy source distributed generation and distribution network.

Description

technical field [0001] The invention relates to a revenue / cost calculation method, in particular to a cost-benefit analysis method for a renewable energy distributed power generation operation mode. Background technique [0002] Climate change and energy issues have put forward urgent requirements for low-carbon development for countries all over the world. In order to implement the "Renewable Energy Law", implement the State Council's strategic deployment of energy conservation and emission reduction, and enhance the strategic position of the renewable energy industry, relevant departments have successively issued a series of planning, implementation policies and funding subsidy policies related to distributed power generation. The market for renewable energy power generation is expanding rapidly. But who should operate distributed power generation, and which operation mode is more reasonable? This is not only an economic problem that needs to be solved urgently, but also...
