Abstract
An alternative power flow formulation, called linear power flow or “dc” power flow (DCPF), consists in the consideration of some simplifications regarding the network representation, leading to a linear problem formulation of low-cost computational performance, and reasonable accuracy. The distribution factors developed from the linear formulation of the power flow problem represent a sensitivity relation between system variables and have a variety of applications. Usually, the power transfer distribution factors (PTDF) are calculated based on the fact that all the power unbalance will be absorbed by the system’s reference bus. This paper proposes a new formulation of the PTDF to perform a more realistic analysis of a system’s operation, based on the linear power flow methodology and the generator’s participation factors. This formulation is then applied to an optimization problem to maximize wind power penetration in an 11-bus test system and the IEEE 118-bus system. The results are compared to those obtained by the original PTDF formulation to determine the new approach benefits. The results presented validate and indicate the effectiveness of the proposed technique.
