In this paper, an integration of a wind farm designed at the installation site of a new city with conventional power generation (CPG) is presented. Two scenarios are suggested to integrate this wind farm with CPG. The impact of this integration on the economic operation of the electrical network is studied using two proposed scenarios. Also, the impact of this integration on the reliable operation of the electrical network is introduced. A long-term load forecasting of the Egyptian electrical network is presented to be helpful in introducing the impact of wind farm integration on the reliable operation of the electrical network. The impact of wind energy integration on economic and reliable operation of electrical networks is applied to the new Borg El-Arab city in Egypt. The results show the capability of the two proposed scenarios.
