Medium term Planning of Strategic Consumer in Competitive Electricity Markets Under Uncertainty

This paper propses a novel framework for medium term planning of strategic consumer in both the future and spot market under uncertainty. The strategic behavior of a strategic consumer is determined based on optimal bidding to the spot market and the best selling in the future market to maximize expected profit. The uncertainty in procedurs offer curves is also modeled via sets of scenarios. The problem is modeled as a two-stage bi-level stochastic optimization problem, where in the first stage the demand purchased from the future market is obtained and in the second stage the required demands which should be purchased from the spot market, are calculated as stochastic variable. The primary two stage bi-level problem is changed to a single stage bi-level optimization problem by using KKT conditions, that renders to a single level problem that known as a mathematical program with equilibrium constraints (MPEC). In order to assess the proposed framework, the proposed model is examined on the transmission network of MAZANDARAN regional electric company (MREC) and results are reported and discussed in several cases.
