In recent years, the penetration of renewable power generation has increased substantially, and is expected to grow in the future. These renewable energy sources are environmentally friendlier compared to the conventional thermal energy sources. Wind and solar energy sources are variable as their electrical power generation varies based on the availability of wind and sun. The load demand is also varies with time, and our power system is designed to handle that variability.The aim of electric supply utility has been identified as to provide the smooth and adequate electric energy to the consumers without any disturbances. Here, one thing should be ensured that electrical power is generated with minimum generation cost. Hence in order to achieve an economic operation, the total demand must be appropriately shared among the all generating units. This research work aims to solve Economic load dispatch Using POWER WORLD SIMULATOR Software.This minimize the total generation cost for the system with satisfied all equality and inequality constraints.
