Calculation of new energy maximum access capacity and design of software platform

Abstract

In view of more and more new energy access to the power grid, this paper proposes a new energy maximum access capacity calculation method, which considers four factors: voltage fluctuation, voltage deviation, harmonic current and transmission capacity. In addition, it develops a set of computing software platform. The platform is based on Python language. The input format file of the platform is a common excel file, which is simple, convenient, flexible and easy to operate. The platform can calculate the maximum access capacity of new energy under the specific grid structure, and give the reasons for limiting access only after inputting the line parameters, new energy parameters, node parameters, transformer parameters, etc.
