Distributed Small Hydro Turbine Governor Modeling and Identification for Advanced Power System Studies

Advanced power system dynamic studies depend on network components model specifications. Distributed hydro generation as a key part of power generation should be taken into account in such analysis. An exact model for generating units that can simulate the unit response in a wide operating range is an important aspect of dynamic studies. Consequently, this paper aims to propose an inclusive model for the hydro turbine governor system. This nonlinear model considers the nonlinear relation between water flow, gate position, and the generated power. Moreover, the proposed model will be analyzed utilizing operational data from a 10.5 MWA small hydro unit. Identification tests have been conducted on the unit and the genetic algorithm (GA) was deployed to extract the unknown parameters. Moreover, validation tests were exploited to assess the effectiveness of the proposed model.
