Applying Genetic Algorithm to Adjustment PID Coefficients in Order to Power Control of Micro-Turbine in Island Condition

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 microturbine, during system load variations. Micro-turbine output power should be control 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 Genetic Algorithm. Simulation results are done for various loads in time domain, and the results show the efficiency of the proposed controller.
