Abstract:
The importance of distribution networks from the perspective of the natural monopoly has been caused regulators attention to the behavior of the electricity distribution companies (EDCs). Regulators in order to control prices, performance-based regulation (PBR) in the electricity distribution companies were implemented. Although this pricing model increases the efficiency of the electricity distribution companies, but strictly quality of service, including reliability is jeopardized. In this context, motivational model using the theory of penalty and reward based on competition in the performance-based regulation is to improve the reliability based on network parameters. The reward and penalty scheme (RPS) rewards electric distribution companies for providing good performance in terms of reliability and penalizes companies with providing poor performance. To create competition, distribution companies clustering, analytic hierarchy process (AHP) and productivity factor has been used. By means of clustering, the similar distribution companies categorized into one cluster and by using the AHP, score of internal and external factors on reliability index were specified and designing RPS for each company in that cluster. In the proposed model, more than one reliability index can be considered. This model is designed in such a way that the penalties received from EDCs and the rewards paid to EDCs. Then, a decision making model with an objective function of the companies investment costs, the amount of reward and penalty and imposed cost on the EDCs due to blackout to assess RPS and define parameters of scheme for the next year. The decision model determine the investment cost, imposed cost and optimal failure rate of companies equipment. Finally, using information from the investment and imposed costs, new parameters of RPS are determined. As a result of this scheme is called dynamic PBR. Also, a method for evaluating investment decisions is presented when a RPS is applied to the EDCs. Using the proposed method, the best investment candidate in terms of cost-benefit rate is selected.
