Abstract The proportion of green energy like solar energy in the construction of distributed network is growing。 The study on the distribution network connected with solar power generation is a hot topic, but the research on the impact of the loss of distribution network connected with photovoltaic is relatively weak。
Firstly, the paper introduces the types and promising applications of solar power system , and then summarizes the results of the optimization of distribution network in the last decade。 Secondly, the paper analyses the influence of the capacity, position and operation mode of photovoltaic on the distribution network loss by establishing the ideal model。 Finally, it establishes the actual distribution network model in ship power system based on the distribution network load characteristics。 Compared with various power flow calculation algorithm, it takes the Newton-Raphson power algorithm, which has high convergence speed and precision, to determine the optimal configuration method of photovoltaic in distribution network。
Under the background of maritime strategy of our country, the conclusions can provide a reference for the rational use and allocation of solar energy, wind energy and other green energy in the complex distribution network in ship power system, so as to reduce the energy consumption and economic expenditures。 The article also proposes a new scheme to reduce the power loss of distribution network based on the support vector machine and Taboo search algorithm for the next step。
