支持海量新能源接入的稳控系统架构及控制技术研究OA

In response to the challenges of grid security and dynamic stability control posed by the integration of massive amount of new energy,this paper proposes a four-tier hierarchical and zoned precision control system architecture consisting of"precision control master station-regional master station-control substation-control terminal",clarifies the functional orientation of devices at each level,optimizes precision control technology,and provides real-time statistics on the dynamic off-grid capacity of new energy to correct switching instructions.Finally,the paper proposes precision control technologies based on multi-objective dynamic optimization and multi-dimensional coordination to achieve precise and coordinated control of multiple resources such as DC,hydro power,thermal power,wind power,photovoltaic power and energy storage,thereby enhancing the safe and stable operation capacity of the power grid in response to faults.
