Economic Optimization of blackout management in electricity distribution networks

This article deals with the optimization of blackout management methods in electricity distribution networks. For this purpose, keying methods, the use of distributed production, and load response have been examined from an economic perspective. For this economic analysis, the cost of a power outage, which includes the cost of human resources, vehicles, and undistributed energy, has been calculated. Considering the key role of duration and unsupplied load in the cost of a power outage, outage management solutions have been modeled. Then, the effect of important parameters such as electricity price has been investigated by sensitivity analysis. The proposed model has been implemented in the Big Tehran Electricity Distribution Company. In the first part, the economic modeling of power outages in the distribution network is introduced. The model calculates things like fines set by the government, the cost of human resources, accident vehicles, and the cost of automation of distribution stations. In the second part, fines and temporary energy supply are optimized. Two approaches are considered for the short supply of energy. The first method is demand-based and load-reduction in reward returns. The second method is to purchase power from distributed sources (DGS) in the outage area. In the third part, the sensitivity of the temporary energy supply to the price provided by the distribution company is considered and its effect on optimization is investigated.
