Simulation of Electrical Power Systems of Greece (Crete) Using the InterPSS

The electrical power system network is a highly complex and extensive entity, particularly when incorporating distributed generation, renewable energy sources, and energy storage devices.This research examines the load flow analysis of the Crete electrical grid using the Internet Technology based Power System Simulator (InterPSS).The Crete electrical network, consisting of 16 buses, was simulated under two scenarios.In the first scenario, the loads absorb 81.5% of their maximum power and 100% of the wind generation.In the second scenario, the loads remain the same, but the wind generation is multiplied by a factor of 5.4, resulting in a total of 1000MW=10 P.U.The results show that in the first scenario, the voltages remain within permissible limits, and no power flow overloading occurs in the network branches, ensuring that the system operates without issues.However, in the second scenario, although the voltage remains within permissible limits, overloading is observed in several branches, making it possible for the system to operate under these conditions.
