Optimization dispatching method of wind power plant containing distributed power flow controller

Abstract

The invention proposes an optimization dispatching method of a wind power plant containing a distributed power flow controller. The optimization dispatching method comprises the steps of firstly, making a day-ahead dispatching plan by taking minimum power generation cost as a target according to a pre-built distributed power flow controller model and a constraint condition; secondly, correcting apower generation plane and a running control strategy of the distributed power flow controller in real time from a current time fracture surface to a next dispatching moment in real time according tothe day-ahead dispatching plane and wind power forecast error; and finally, making a real-time dispatching plan by taking lowest power generation cost within unit frame as an optimization target, anddispatching a wind power plant according to the real-time dispatching plane. The invention proposes the optimization dispatching method, which is economic, safe and more accurate, for the wind power plant; by making the reasonable power generation plan, the running economy of the system is improved, and an unnecessary wind abandoning phenomenon is reduced; the wind power absorption level and the power grid running economy are effectively improved, and a solution idea is provided for economic and safe dispatching running of a future power grid.

Description

technical field [0001] The invention relates to an optimal scheduling method of a wind farm including a distributed power flow controller, belonging to the field of new energy and the technical field of flexible AC transmission. Background technique [0002] The increasingly prominent energy crisis and carbon emission issues make renewable energy represented by wind power maintain a rapid development trend in countries all over the world. However, after large-scale wind power is connected to the grid, its intermittence and volatility bring great challenges to the power flow control and dispatch of the power system. As the penetration rate of wind power continues to increase in some areas, the safety and stability of the grid caused by wind power grid integration cannot be ignored. If a reasonable power generation plan cannot be formulated, unnecessary wind curtailment will occur and system operating costs will increase. Therefore, how to accommodate wind power as much as po...

However, after large-scale wind power is connected to the grid, its intermittency and volatility bring great challenges to the power flow control and dispatch of the power system.

As the penetration rate of wind power in some areas continues to increase, the security and stability of the grid caused by wind power grid integration cannot be ignored. If a reasonable power generation plan cannot be formulated, unnecessary wind curtailment will occur and system operating costs will increase.
