Coordinated Intelligent Operation and Emergency Control of Electric Power Systems

Abstract

This chapter presents the following approaches and developments: (1) the approach to power system state estimation based on structural and functional decomposition. PMU measurements are used to coordinate the solutions obtained in individual areas; (2) a non-iterative method to calculate voltage magnitude and phase at all the buses, allowing the state parameters of EPS to be obtained fast enough; (3) the approach to the super short-term forecasting of state variables on the basis of neural network technologies and algorithms of nonlinear optimization that is realized in the ANAPRO software; (4) an analysis of the possibility of determining weak ties and cut sets in EPS; (5) a control system based on the multi-agent technique; (6) the development of selective automatic systems intended to prevent and eliminate out-of-step operation on the basis of synchronized voltage phase measurements obtained from Phasor Measurement Units.
