In this paper, a novel framework is proposed to solve distributed generation (DG) expansion planning problem in sub-transmission substations considering expansions of transmission substation capacities in the presence of incentives. The prposed model includes both the firm contract and capacity payment as incentive options. A bi-level model is presented for the problem, where the upper level consists of optimal decision of investor through maximizing profit, while market clearing and substation expansion are considered in lower level. Due to existing of binary variable in the lower level problem and therefore its non-convexity, it is not possible to convert the bi-level problem in to a single level, so-called mathematical problem with equilibrium constraints (MPEC). Thus, an algorithm which gains the combination of enumeration and mathematical optimization is used to tackle with the non-convexity. In the proposed approach, according a few number of expansion strategies of substation upgrading, all strategies are considered and a MILP is solved for each strategy. The efficieancy of the proposed model is examined on a six-bus network and on a part of subtransmission network of MAZANDARAN regional electric company (MREC).
