Joint planning method for wind power plant, power transmission network and energy storage based on chance-constrained IGDT

Abstract

The invention discloses a joint planning method for a wind power plant, a power transmission network and energy storage based on a chance-constrained IGDT, which comprises the steps of firstly acquiring wind power plant planning data, energy storage planning data, basic technical data of the system, system operation constraint data and system operation prediction data, and then constructing a joint planning model objective function of the building lower bound of the wind power plant, and building model decision-making constraints; then constructing a joint planning model objective function ofthe building upper bound of the wind power plant, and building model constraints; respectively solving the joint planning model objective functions of the building upper bound and lower bound of the wind power plant according to the a solving algorithm based on the Benders decomposition strategy, and acquiring the optimal planning solution for planning. Compared with a single-aspect planning method, the joint planning method provided by the invention has better economy and wind power utilization efficiency and can better meet various requirements of the system operation, thereby greatly improving the consumption level of wind power, and increasing the investment income of wind power.

Description

technical field [0001] The invention belongs to the technical field of grid planning in electric power systems, and in particular relates to a wind farm-transmission network-energy storage joint planning method based on opportunity-constrained IGDT. Background technique [0002] Under the general environment of advocating low-carbon economic development, the development of my country's power system is in a special period of transition to green energy. Due to the high maturity of the wind power industry at the technical and market levels, and the fact that the Chinese government also encourages investment and operation of wind power at the policy level, wind power is currently one of the most rapidly developing renewable energy sources. The installed capacity is second only to coal power and hydropower, and it is the third largest power source in my country. However, it is worth noting that due to the significant randomness and volatility of wind power generation, as the pene...

Problems solved by technology

The result of deterministic wind farm investment and construction obtained in this way is not enough to guide the development of wind power, and it ignores many key information that affect the investment and construction of wind farms, such as the proportion of wind power consumption and profitability of each invested wind farm.
