Researching exploitation regime of long term scheduled hydropower sources in Vietnam power system

Abstract

     In the composition of Vietnam power system, hydropower has a high proportion. Most medium and large hydropower stations in the system have reservoir for long-term scheduling. One of scheduling characteristics of these reservoirs is the impact of the impact which affects the operational efficiency of the whole system. This article presents the scientific basis and regime to exploit the long-term scheduled hydropower sources in design as well as in operation to improve the operational efficiency of hydropower, thereby reducing system costs. The obtained results from application for the My Ly hydropower station show the effectiveness of the methodology.
