Along with the gradually lack of the fossil fuels, people pay more and more attention to the use of renewable energy. Distributed power supply of a large number of interconnection affects the distribution network power flow direction and size a lot. Thus, the protection setting values of the distribution network line are not accurate, which lead to the refusing action or misoperation. This article uses compensating coefficient based on the consideration of adaptive protection algorithm of distribution network protection value setting, and operate simulation. The simulation results show that this algorithm of adaptive protection is good with different distributed power grid capacity and right protection setting values.

One of the major concerns for the interconnection of distributed generation (DG) to distribution network is the technical issues associated from the connection. In the conventional distribution network, the power flow is uni-directional, from centralizes power plants to transmission and then to distribution before it supplied to the customer. However, with the anticipated amount of DG connected at distribution network, power flow is no longer uni-directional. Due to this fact, it is crucial to perform power system study to ensure the system stability is not deteriorating. This paper discusses the dynamic analysis to examine the electromechanical transient responses of the DG unit under various system faults and contingency situations. This contents presented in this paper can facilitate DG developers, consultants, contractor and utility engineer in planning for the new connection of DG to the distribution network.

As distribution network is of radial pattern, the forward and backward substitution algorithm and its variations are widely used for radial distribution network power flow calculation, which needs to form associated admittance matrix and matrix operations. This paper proposes a sequential numbering power flow calculation algorithm for distribution network. Based on the graph theory of nodes, the proposed method can handles multiple branches radiation network.. In the simulation test, our proposed algorithm is applied to a typical radial distribution network in order to verify the efficacy on power flow calculation. The results show that the sequential numbering power flow algorithm has good performance in terms of convergence rate and reliability.
