摘要：

Considering the PV output, load change and the electric price has obvious cycle for one day, the operation optimization model for photovoltaic system with time coupled batteries was established. The model is nonlinear model or rather piecewise linear model in the whole optimization cycle. In order to use efficient linear programming algorithm to solve it, the model is transformed into the global equivalent linear model by piecewise splitting some control variables and equivalently rewrite some constraints. Compared with the original nonlinear model, the transformed linear model can not only get the best operation scheme under both time-of-use price and real-time price, but also can be solved very quickly. So it can be used in the day-ahead operation scheme as well as the real time optimization. By varying the depreciation coefficient, the profitable depreciation or the profitable battery cost is predicted with the actual time-of-use electricity tariff in a province in Southeast China. © 2018, Editorial Board of Acta Energiae Solaris Sinica.
