摘要： A power system energy management system with security constrained automatic generation control (SCAGC) is disclosed wherein the power generation output and branch power flow are constrained by security limit. A sub-optimization model is used to calculate SCAGC for each control area in parallel. Graph computing is applied to solve the SCAGC by simplex approach in hierarchical parallel and nodal parallel. The SCAGC is solved heuristically first by combining the equal incremental fuel cost ratio and generation shift factor, and if the heuristics do not converge, a simplex method is used to solve the SCAGC.

摘要： A power system energy management system with dynamic state estimation (DSE) is disclosed wherein system dynamic states are estimated using SCADA measurements, PMU measurements, signals of controllers, digital recorders, protection devices, and smart electronic devices. The DSE is solved first by Unscented Kalman Filter, and if the Unscented Kalman Filter is failed, weighted lease square is used to solve the DSE. If weighted lease square is failed, integration method is used to calculate the dynamic states. In another aspect, Unscented Kalman Filter, weighted lease square, and integration calculation are applied to solve the DSE by nodal parallel computing for each generation system.
