Abstract :
Intentional islanding (referred to a micro-grid) holds promise to improve power system reliability and power quality due to its more flexible control. To operate intentional islanding successfully, more efficient and robust control methods are required. A new concept is developed as an enhancement to the application of optimal load shedding for corrective control to support an islanded power system. The new proposal is comprised of two major stages in which one nonlinear optimization problem and one linear integer optimization problem are formulated. Numerical simulations conducted on a 15-bus system have demonstrated the performance of the new algorithm.
