A Comparative Study Between Priority Assigning Method And Lambda Iteration Method For Unit Commitment Problems

Abstract

Our project report basically focuses on the Unit Commitment Scheduling of Thermal power stations so as to obtain the most optimized way of power production fulfilling the total load requirements, transmission losses and at a same time integrating all the safety measures required. The Unit Commitment is a complex decision making process because of multiple constraints which may not be violated while finding the Optimal Commitment Schedule .This report also deals with the Economic Load Dispatch through Equal Incremental Cost of different operating units so as to have the most efficient and economical generation from different units with sufficient reserve capacity to meet any abnormal operating conditions. The goal of the objective function is in cost reduction ,so we use the economic dispatch using the lambda iteration method when we calculate the production cost. Methods for assigning priority to different generating units are also discussed in brief. Finally we wish to solve a load flow solution using Two Different Approaches and compare their result to get the most optimized way of generation and verify it using MATLAB.
