Conventional power distribution system is AC in nature. Due to scarcity of the non-renewable energy sources and also due to the lack of its supply, the dependency on the renewable energy sources is increasing, which is generally DC in nature, is included in the existing system to make the overall system hybrid in nature. Here an alternative algorithm is used, capable of solving the load flow problem in such a system to overcome the problem of conventional method. The proposed modified Backward-Forward Sweep (BFS) algorithm in this book is basically the derivative free load flow method. This method is also useful in case of DC microgrid to solve the load flow problem. As the test system is hybrid in nature so there is necessity of modeling the interlinking converter. The load flow problem in case of islanded operation is also taken into consideration and also removes with the help of this proposed method.
