Abstract :
Power flow calculation of shipboard power system aims at determining operation conditions of the whole system, such as voltages of every bus, power distribution and power loss in shipboard grid, according to given operation conditions and network structure. Ladder-shaped shipboard power system is a newly developed network with greater reliability and flexibility. In this paper, a parallel power flow calculation algorithm is proposed which specifically considers the features of ladder shipboard power system. This algorithm divides the whole system into concentrated power supply network and several distribution subnets, and adopts node potential method and forward-backward sweep calculation to different calculation levels respectively. The test results indicate that this parallel algorithm has better performance of convergence and greater flexibility.
