Security Check Service and Practical Technique Based on Smart Grid Dispatching and Control Systems

Security check is an important link for power system safety. Based on the service bus and parallel computation technology of the smart grid dispatching and control system, service-oriented security check is studied and developed to provide customizable security check service for day-ahead scheduling, schedule adjustment and power grid dispatching operation. Scheduled power flow is the key function in security check. According to the hierarchical dispatching mode of China power grid, a scheduled power flow algorithm based on multi-section power flow control technology is proposed. Voltage and reactive power automatic adjustment and intelligent adjustment for non-convergence of power flow are used to improve convergence and rationality. Day-ahead schedule security check for multi-level dispatching is studied. The practicability is enhanced by checking schedule data and counting some technical indices.
