Voltage Stability Enhancement Considering Operation of Smart Loads

Article Preview

Abstract:

Environmental and economical constrains to build more aggregate bulk power plants and transmission lines besides slow improvement of DG in compare with fast growth of demand, resulted in operation of heavily loaded power grids near their stability limits. Meanwhile, a disturbance occurrence may lead to voltage instability more probably than ever before. A smart methodology of load shedding, based on optimized fuzzy inference logic, is evaluated in this paper to mitigate instability state of the power system. The result indicates more reliable voltage maintenance while using optimized membership function in our defined fuzzy logic system
