Abstract A power system in Marsa Alam is an example of an isolated diesel power system in the remote regions of Egypt with no connection to the national grid. This area is expecting a rapid increase in electricity demand, because of exclusive resorts and infrastructure developments in the coming years. The local authority in Marsa Alam has an interest in their future developments to combine its diesel power generation with wind power generation. In year 2007 the maximum power demand was recorded to approximately 8 MW. This demand is expected to increase rapidly, due to the construction work of the resorts is ending and tourists will be settling into the newly build resorts. To ensure the same reliability of electricity supply with wind turbines connected to their existing power system, it’s important to predict the performance of the power system with wind turbines under a wide range of conditions. One of the concerns regarding the wind power integration is the stability of the isolated power system and its reliability due to potential mismatch between fluctuations in the wind and the variations in the load. The concern depends greatly on the level of wind penetration in the isolated power system. A high level of wind penetration will allow more diesel fuel savings but creates a challenge regarding the power stability, power quality and control strategies of the power system and its operations. The main focus of the project is to analyze a scenario for the existing isolated diesel power system in year 2010 and furthermore simulate the frequency and voltage variations in the power system at different wind power penetration levels. In case of frequency improvement, a method is applied to evaluate the potential of using demand as frequency control. A simplified grid model of the isolated diesel power system and a double-fed-induction-generator (DFIG) wind turbine model are developed in the simulation tool, DIgsilent PowerFactory 13.2. With the estimated isolated power system for year 2010, three phases of wind power integration has been proposed. The rated output power of the wind farm in the three phases are; 6.5 MW, 13 MW and 19.5 MW respectively. From the three phases a suitable target is suggested for year 2010.
