The authors describe an expert system which assists the security control of an electric power system. The expert system first judges the power system operating conditions based on its voltage profile and line flow patterns and then displays possible control actions to be chosen by operators. The salient features of this expert system are: (1) power system(More)
A power system, under heavily loaded conditions, is at high risks of probable line outage and consequent voltage instability problem. Real power loss and voltage deviation minimization are reliable indicators of voltage security of power networks. This paper proposes a Particle Swarm Optimization (PSO) based optimal location and sizing of Static Var(More)
