Abstract

The ever increasing energy demand, along with the necessity of cost reduction and higher reliability requirements, are driving the modern power systems towards Distributed Generation (DG) as an alternative to the expansion of the current energy distribution systems. This paper is aimed to introduce the new controller in order to control of output power of one of the most important types of distributed generation namely micro-turbine, during system load variations. Micro-turbine output power should be controlled against the load variations in island mode condition and a controller should be designed for this purpose. Here, the PID controller is used which its coefficients are optimized based on ‘evolutionary programming’ algorithm. Simulation results are done for various loads in time domain, and the results show the efficiency of the proposed controller.

Key words: Micro-turbine, evolutionary programming, distributed generation, controller design, optimization.
