RESEARCH AND DESIGN OF A MATHEMATICAL MODEL FOR AN INTERCONNECTED HYDROPOWER SYSTEM IN THE STABILIZATION PROBLEM OF TURBINE SPEED

Abstract

In the current power system, the adjustment of the frequency of the grid
stability when the load changes to ensure power quality is a highly
important control problem. The power system has several types of primary
sources such as thermal power, nuclear power, hydroelectric, solar power
and wind power. Hydroelectricity always accounts for a relatively large
amount of capacity on the total grid capacity. Building a mathematical model
of the connected hydroelectric system is a very important step in designing
the hydro turbine controller to stabilize the grid frequency when the load
changes. From the investigation of mathematical modeling, it is possible to
apply efficient net frequency control strategies for the interconnected
hydropower system in reality.
