Abstract:

In view of the limitation of Manhattan algorithm in solving the problem of locating the combiner box, a comprehensive method for cable loss and net present value is proposed. Taking into account the factors such as cable consumption, cost, DC cable loss, power generation in 20 years and revenue, specific cases are calculated and the the results of different schemes are compared and analyzed. The results show that this method can effectively reduce the cable consumption, cut DC cable loss, improve system efficiency, maximize the generation benefits and make up for the shortcomings of the single algorithm. It can provide a reference for the optimal layout of the combiner box.
