optimization of Wind Power Grid Connection in Multi-Source and Multi-Region Power Generation System Based on Peak Adjustment Margin

摘要

Multi-source and multi-region combined power generation control system refers to a system that includes wind, light, storage, fire, nuclear energy and other energy sources existing in multiple regions at the same time and realizing scheduling control at different levels. Electric system, the author of this paper stroke in load when the load power margin of the whole system is analyzed, considering the wind power grid has increased the difficulty of the system active scheduling, in order to coordinate system operation reliability, economy and the contradiction between the question of benefits of wind power, put forward the 24 point load margin index, from the Angle of peak shaving, determine the dynamic positive and negative rotating standby and wind power grid power system, and build the system with target of minimizing the total operation cost, water, coal prices running cost, wind abandon the wind punishment cost as well as the system backup punishment cost of wind power grid coordinate optimization scheduling model. For this model, Matlab is used for simulation verification. The results show that the proposed model provides an effective method to solve the problem of wind power grid-connected operation.
