Unit commitment is one of the pertinent analyses required in the scheduling and dispatch of power system. Various mathematical techniques have been developed to cater for the requirements of solving the unit commitment problems in power system. In scheduling of power generation, various requirements have been detailed out by countries in the forms of standards and codes. For Malaysian electricity sector, the process of scheduling and dispatch is governed by the requirements specified in the established Malaysia Grid Code 2006. This newly revised Code has detailed out the requirements and necessary procedure for the Unit Commitment process for the Malaysia electrical energy environment. The main objective of the project is to develop a systematic method in solving unit commitment problem in general and for Malaysia electricity sector in particular. The second objective is to utilize the method in order to minimize generating cost and at the same time fulfilling all the constraints related to the delivery of electrical energy from the generating companies to the consumers. The specific considerations to the requirements of the Malaysian Grid Code are fulfilling the scope of the project. The method has been programmed using Turbo Pascal language and tested on several test systems. The Dynamic Programming method has been chosen to solve the unit commitment process. The program has been successful applied to run the system base on Malaysia Grid Code requirement. The generations have been able to be optimized the operation of the system base on the load demand for the given day. The generating costs of the generation have been minimized besides fulfilling the load demands. Eventually, the program is capable to be used to analyze the Malaysia power system.
