Comparative Analysis of Optimal Generation Scheduling in Modern Power Systems Considering Renewable Energy Resources

Abstract

Majority of electrical power systems are aiming to reduce their dependencies towards fossil fuels in the face of growing concerns for environment, increasing fuel price, energy conservation, and sustainable development. As a result, there has been steady increase in renewable power generation in power systems all over the world and expected to grow further in future. Renewable energy sources (RES) have grown considerably in the last decade.

However, there are still some serious concerns about RES technologies and their implementation into the exiting energy production and distribution systems. The main issue is the intermittent nature of many RES. In particular, wind and solar power plants cannot produce power steadily since wind speed and solar radiation change during the day and the year.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 AND MAT POWER SIMULATOR Software.This minimize the total generation cost for the system with satisfied all equality and inequality constraints.
