Hydropower Cooperation for Firm Power Production of Hydropower Plants System in Central 1 Region of Laos People's Democratic Republic

Abstract

This paper presents multi-hydropower plants cooperation to produce the appropriate power energy of the hydroelectric power plant system in the central region 1 of the Lao People's Democratic Republic (Laos PDR). The main objective is to guarantee the stable firm power energy supply to the customer in domestic under constraints such as water inflow, water outflow, water storage, and power production of each hydropower plants. The case study considered 10 hydropower plants which the hydropower’s technical data and consecutive hydrological daily inflow data year 2018 of each hydropower plants were selected to simulation firm power production. The linear programming is used to solve this cooperation problem and this research use MATLAB program for simulation. The simulation result has shown that multi-hydropower plants cooperation firm power production is 14,520 mw per month. and maximum power production is 252,732 MW per year (for the year 2018). The cooperation model could help the operator’s decision in the purchase of sale electrical energy as firm and semi-firm energy. Moreover, it could apply to another case.
