Fuzzy Logic Controller for a Hydro Pumped Storage Plant to Provide Frequency Regulation in an Isolated Hybrid Micro-Grid
Abstract
The operation of isolated micro-grids requires that such systems must be able to regulate the system frequency also in addition to voltage. The combined operation of a reversible hydro pumped storage unit, a wind generator, a diesel generator and a dump load is analyzed in this study. The main balancing mechanism of the micro-grid is the hydro pumped storage facility. A fuzzy inference system is used to control this primary component to provide frequency regulation. Also, a supervisory controller is implemented to select the operation of other balancing mechanisms in order to support the operation of the hydro pumped storage. Model of the proposed isolated hybrid micro-grid is developed and the designed controllers are tested in this thesis. By monitoring the system frequency and active power of various components, it is concluded that the proposed frequency control scheme provides a reliable frequency regulation while reducing the frequency deviation during disturbances.
