After installing new energy sources such as photovoltaic and wind turbines in microgrid, the net load of microgrid will be changed completely. It is possible to further deteriorate the net load curve of microgrid by adopting time-of-use under the original time division. Considering this phenomenon, the time-of-use period is divided into the planning stage of microgrid, a two-tier model of coordinated planning and time-division of microgrid is constructed. The upper level aims to maximize the NPV of revenue in the lifetime of microgrid, and coordinates the planning of power supply capacity and time-of-use price. Pairs Sum model is used in the lower level to divide the time period of the net load value obtained by the upper level. The two-level model is solved by using non-linear programming tools. The conventional programming scheme is introduced into the example to verify the effectiveness of the model. The goal of maximizing the total revenue of microgrid can be achieved by considering the time division of time-of-use in the planning stage of microgrid. The relationship between the total revenue of microgrid, peak-valley price ratio constraints and power abandonment penalties is also discussed.
