en A New Approach for Accurate Pricing of Reactive Power and Its Application to Cost Allocation in Deregulated Electricity Markets قدرت Power پژوهشي Research <p>Reactive power management plays an essential role in the secure operation of the power system as an ancillary service.<br> Although in electricity markets, the particular attention is paid to active power, the reactive power also plays an<br> important on total generation costs of electricity. On the other hand, as it is mainly confined to local consumption, to<br> avoid market power and maintain the secure operation of a power system, accurate reactive power pricing and cost<br> allocation methods are essential. It has been a challenging problem during the past decade. However, most methods<br> proposed so far for reactive power pricing, are essentially based on empirical approximations. In this paper a new<br> method for reactive power cost allocation is proposed. The method is based on the calculation of accurate cost imposed<br> on generators supporting reactive power. The proposed method is fair, accurate and realistic and it can be formulated<br> very easily. Furthermore, a new approach based on tracing algorithm is proposed for pricing of reactive power which<br> considers the cost of both active and reactive losses allocated to each generator and cost of capacitor banks. To validate<br> the performance of the proposed method, it is applied to both 9-bus and 30-bus IEEE test systems.</p> <p>Reactive power management plays an essential role in the secure operation of the power system as an ancillary service.<br> Although in electricity markets, the particular attention is paid to active power, the reactive power also plays an<br> important on total generation costs of electricity.
