Coordinated optimizing control strategy between power generators and power grid in Inner Mongolia

With the rapid development of the Inner Mongolia power grid, especially wind power capacity continuing to increase, its randomness and volatility put forward higher requirements on the grid to run scheduling. faced of the multi-level, multi-scale, multi-object complex grid, it is the problem to be solved - how to make full use of adjustable system resources and means of automation equipment, optimizing the operating status of the grid to achieve the coordination of the active and reactive optimization and distribution to ensure the safety of the grid, stability, economic operation. In view of the existing operating and scheduling technologies of Inner Mongolia power grid and drawing on the idea of hybrid control system, this article proposes a control strategy of machine net coordination and optimization based on layered event-driven control. This strategy takes into account indicators as economy, safety and quality of the system. It establishes a layered event driven control model to realize layered management and regulation of the whole system. It can automatically judge and select the optimal (or quasi optimal or appropriate) control mode, thus ensuring the sound dynamic quality of the entire power system while improving its stability and reactive power flow to reduce the network loss. Based on the control theory system, we conducted simulation analysis of Inner Mongolia power grid. The result reveals that the control strategy can not only keep contact line exchange power and central node voltage within permitted range, but also improve the economy and safety of the system. The simulation analysis proves that our control strategy can guarantee the safe, sound and economic operation of the system. It can elevate the automatic control level of Inner Mongolia power grid and guide fine adjustment of active and reactive power.
