Abstract
Operation of an isolated hybrid micro-grid requires a system to be capable of regulating the system frequency as well as the voltage. The operation of a hydro power plant combined with a wind power plant and a solar power plant is analyzed in this thesis. The main balancing mechanism of the proposed hybrid micro-grid is the hydro power plant. Speed governor of hydro power plant and wind pitch controller of wind power plant are implemented using both conventional PI and Fuzzy logic based controllers. A supervisory controller, that will supervise individual controllers and determine the desired power generation of hydro and wind power generating units, is also proposed. By monitoring the system frequency, voltage and active power of various power generating units under various operating conditions, it is concluded that the proposed control scheme provides reliable system frequency and voltage regulation, and energy management.
