Pumped storage power plants can effectively guarantee the healthy development of energy and promote energy transformation and green development. The calculation accuracy is directly related to the flood control safety of the reservoir. The current storage calculation method of storage capacity is inefficient and complicated resulting in deviations between calculated values and actual storage capacity. The paper is devoted to the problem of efficiency and quality of capacity calculation in the planning and design stage of pumped storage power plants. A toolkit MicroPSCal is developed based on MicroStation software to simulate and calculate the corresponding storage capacity of different elevations and draw the storage capacity curve, which can be applied in the actual planning and design process of pumped storage power stations. The results of the calculation showed that this method can make full use of terrain accuracy to achieve high-precision calculation of reservoir capacity of different elevations and automatically draw high-quality storage curves. Compared with traditional storage capacity calculation methods, calculation time was reduced from 18 hours to 45 minutes. This method has obvious advantages and provides a new technical idea for storage capacity calculation during the planning and design of pumped storage power plants.
