Power System Stability and Load Sharing in Distributed Generation

Majumder, Ritwik, Ghosh, Arindam, Ledwich, Gerard F., & Zare, Firuz (2008) Power System Stability and Load Sharing in Distributed Generation. In POWERCON2008 & 2008 IEEE Power India Conference, October 12 - 15, 2008, New Delhi, India.


This paper describes control methods for proper load sharing between parallel converters connected to microgrid in a distributed generation system. The system stability is investigated during load sharing for safe operation and proper control. The dynamic response of the system is compared under different load conditions. Both inertia-less and inertial loads are considered in grid connected and islanded modes. A smooth transition between the grid connected and islanded mode is achieved. Its efficacy has been validated through simulation for various operating conditions. The impact of high values of real and reactive power droop controller gains on overall system stability is investigated. For a stable operation and quick attainment of steady state, an adaptive droop controller is proposed. The model of the microgrid power system is simulated in PSCAD.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
