Influence of load model in distribution market emulation

This study presents the results of the implementation of a methodology for electric energy tariff´s calculation approach. Two distinct steps in the calculation approach are described: (i) the flexibility of the price schedule definition so as to permit the establishment of different price schedules for each voltage level concerning their duration as well as their quantity; and (ii) the inclusion of price-elasticity in the revenue reconciliation procedure. Preliminary results show that this approach allows the regulator to precisely establish the regulatory revenues predicted in the tariff-revision processes. It also permits tariffs to be effectively used as load management mechanisms as well as maximize consumer welfare. The methodology described produces tariffs close to the costs endured by the DISCO besides not losing the adequate economic signal for the distribution network efficient use.
