Dynamics of diesel and wind turbine generators on an isolated power system

The paper presents dynamic system analysis of an isolated electric power sy stem consisting of a diesel generator and a wind turbine generator. The 150 kW wind turbine generator is operated in parallel with a diesel generator to serve an average load of 350 kW. Time domain solutions are used to study the performance of the power system. Optimum values of gain settings of th e Proportional-Integral controller (P-I) are obtained by using the integral squared error (ISE) technique. A simple variable structure control (VSC) l ogic is also proposed for improvement of the dynamic performance of the sys tem. (C) 1998 Elsevier Science Ltd. All rights reserved.
