System Indices-Based Congestion Relief Methodologies Using Distributed Generation in Advanced Power System Planning

Distributed Generation technology has been proven to be an effective methodology for power system congestion relief to a certain extent. The advanced Generation, Transmission and Distribution power system planning with effective adoption of distributed generation with prompt utilization of system indices will help to create congestion-free scenarios in the power system network. Power system performance index, PPI, power system performance index contribution of branches (PPICB), Voltage related performance index (VRPI) and voltage performance index contribution of branches (VRPICBs) are the mainly brought system indices in this work. The combined use of power system performance index and voltage related performance index of this scheme will encourage the power system specialists to handle this congestion methodology very effectively. This methodology is applied in the interconnected bus system of the IEEE 14 Bus system, and its validation is done successfully. The applicability of the developed methodology has been tested in a practical system of one of the Supply entities in India.
