In this paper, four scenarios of energy supply for consumers are compared using the proposed objective function and the most appropriate energy methods have been identified. Four energy scenarios are: energy only by the network, the networks and distributed resources, micro-grid systems only and micro grid connected to the upstream network. The objective function for these energy scenarios are calculated and compared for two different load connections, all loads on one feeder and each load on individual feeders. Proposed objective function for each scenario consists of two dimensions, cost and reliability. Cost dimension includes constant cost, current cost and reliability dimension includes non delivered energy for consumers. After conversion into one dimension, the objective function is solved using linear programming. The proposed method in this paper compared with similar methods and these results demonstrate that the method in this paper is more efficient and practical.

In competitive electricity market, maximizing the profit is the main objective in company’s decision making. Hence, Transmission companies (Trans Cos) are not interested in improving reliability and expanding existing structures without financial benefits. On the other hand, consumers demand more reliable and high quality power. In this paper, transmission insurance plan is proposed as an incentive method to improve the reliability of electrical power transmission. In this method, an insurance contract concluded between insurance company and every customer. Insurance company spend a part of its revenue to increases the reliability of the transmission system and also pays for compensation of consumers not supplied energies. The proposed method is studied in a network with six buses. Results show that the proposed method increases network reliability.
