Embodiment

[0095] A. Analysis of load and photovoltaic power generation in the new area:

[0096] 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.

[0097] The total annual radiation of the new district is 1500kWh / m 2 Around, the annual sunshine hours are above 2800h, and the solar energy resource belongs to the "very rich zone" of category II. The installed capacity of solar energy is 13.4MW, the annual power gener...

Abstract

The invention relates to an optimization method of a renewable energy source distribution type power generation operation mode, comprising the following steps of: when determining a distribution type power generation operation mode, carrying out matching analysis on distribution type power generation capacity and a load curve according to factors such as the renewable energy source conditions in a pilot region and regional development planning; carrying out analysis on the feasibility, the advantages and the disadvantages of each of distribution type power generation operation mode, and determining an access scheme and a distribution network power supply scheme of distribution type power generation in different operation modes; calculating a cost composition and an income composition in different operation modes according to boundary conditions, calculation parameters and the like; and taking a time value of money in consider, and calculating a total cost present value, a total income present value, an annual average cost present value, an annual average income present value and an income / cost value PI in the entire life cycle in different operation modes, thereby determining an operation mode with optimal economy. With the adoption of the optimization method, a solid theoretical basis is formulated and established for matching policies related to renewable energy source distribution type power generation and a distribution network.

Description

technical field [0001] The invention relates to an optimization method, in particular to an optimization 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 a political proble...
