This paper presents the market analysis in the interregional congestion management process. It proposes that the market analysis calculates the impact factors in each zone. The assessment of market analysis plays a vital role in the deregulated electricity market. The IEEE 30-bus system is classified into three zones and the most congested zone is identified. The rescheduling of both real and reactive power to minimize the congestion cost is done by using differential evolution krill herd migration algorithm (DEKH). The numerical results on an IEEE 30-bus system is found and the congestion cost is minimized.
