Short Term Schedule of Economic Dispatch and Emission of Hydrothermal System

Abstract

The overall goals of paper will be improved he financial and environmental benefits of the combined operation of hydro and thermal power plant. Considering both of reduction fossil fuel usage and the power generation cost by coal-fired units, the   power generation scheduling problem of the power system with cascade hydropower three stations. The schedule of this problems of cascade hydropower stations are the power generation, the hydropower water consumption, the thermal power generation pollutant emissions, and the total thermal power cost. The schedule dispatch model established by this can not only determine the best output of thermal power and the best water storage and release strategy of hydropower, but also describe the complementary effects of hydropower and thermal power, and fully reflect the concept of energy conservation and benefit. So Genetic Algorithm has been applied to find out the solution of pollutant and economic of hydrothermal plant dispatch. The short term scheduling is determined for studying and to calculate the hydro and thermal power plants. Some of thermal restrictions and hydro restrictions are considered in the processing such as storage limitation, discharge limitation of the reservoir and generation of each unit limitation. The hydrothermal short term schedule calculation has been included 3 hydro units and 3 thermal units from power system. The study case has been gotten the data and the situation in Cambodia
