Energy power planning method suitable for development of high-proportion renewable energy

Abstract

The invention relates to the field of energy power planning and discloses an energy power planning method suitable for development of high-proportion renewable energy. The method comprises the following steps of obtaining related data of current situation and development of a power supply, related data of current situation and development of a power grid, related data of generation energy resourceendowment and related data of an energy power development policy, obtaining maximum load data in a planning period, and obtaining a wind speed, illumination intensity and annual hourly load data in the planning period; building a wind-light load joint scene set through clustering; building a multi-regional and multi-scene energy power development planning model; solving the planning model; and determining power supply construction, a power flow scheme and run statistics. According to the energy power planning method, on the basis of a multi-regional and multi-scene research idea, the multi-regional interconnection development planning research requirements can be met; moderate coupling of energy power planning and operation can also be met through a multi-scene mode; the development planning research practicality of high-proportion renewable energy power is improved; and scientific decision-making of the energy power development department is facilitated.

Description

technical field [0001] The invention relates to the field of energy and power planning, in particular to an energy and power planning method suitable for the development of high proportion renewable energy. Background technique [0002] In the face of increasingly severe climate and environmental problems, the past high-consumption and high-emission energy development model has become unsustainable. It has become a general trend to establish an energy supply system with renewable energy as the mainstay and realize energy clean and low-carbon transformation. Since clean energy is mainly converted into electricity use, in a sense, the power industry is not only in an important position in energy transformation, but also a key link in promoting transformation, and to a certain extent determines the effect and success of transformation. The biggest difference between the high-proportion renewable energy power system and the conventional power system is that wind power and solar ...

AI Technical Summary

Problems solved by technology

[0004] In summary, some existing models and methods treat renewable energy as a traditional power source, and do not deeply analyze the impact of a high proportion of renewable energy on power system planning and operation; although some methods mention a high proportion of renewable power generation, However, the coupling of planning and operation is still neglected; although some methods propose an integrated model of planning and operation simulation, the requirements of operation simulation for future power system information are too complicated, and the degree of practicality is not good.
