Determining Optimal Buses for Implementing Demand Response as an Effective Congestion Management Method
Abstract-Demand response (DR) can be counted as an effective congestion management (CM) method in power systems. However, appointing the optimal buses for the demand response programs (DRPs) implementation is one of the main challenges for the power system operators. In this paper, a new procedure has been developed by which the optimal locations and times of DRPs implementation are determined. Optimal buses are identified based on the power transfer distribution factors (PTDFs), available transfer capability (ATC), and dynamic DC optimal power flow (DDCOPF) problem. Applying the developed method results in reducing lines’ congestion, increasing customers and independent system operator’s (ISO’s) benefits, improving load curve’s characteristics, preventing line outages and black outs, and consequently increasing the network reliability. The proposed method has been applied on the IEEE 39-bus New England test system. Results indicate the effectiveness and practical benefits of the proposed method.
