Embodiment 1

[0083] As shown in the figure, the PSASP / UPI-based energy storage system configuration method for high wind power penetration power grid frequency regulation requirements of the present invention is specifically implemented as follows:

[0084] 1. Application principle of user program UP in UPI environment

[0085] First, the basic working principle of PSASP / UPI. PSASP provides a user program interface (UPI) environment, and users can develop UP programs according to their needs, so that the PSASP function modules and user program modules can work together to complete a certain computing task. In the Windows operating system, the dynamic link library (DLL) support provided by it can be used to realize the interaction between computer language and logic control. The UP written by the user is based on the control array (F1 and F2) set in advance according to the interface specification, and completes the information transfer between the UP program and the PSASP main program. W...

Abstract

The present invention relates to an energy storage system configuration method based on a PSASP / UPI and facing high wind power penetration power grid frequency modulation demands, and belongs to the wind power technology field. The method mainly comprises the development of an energy storage frequency application mathematical model and an energy storage UP under a UPI environment and the making of an energy storage control strategy, and is characterized by utilizing a PSASP software to store energy under the UPI environment to participate in the application of the high wind power penetration system frequency control, simulating in a WSCC-9 example system under the UPI environment, on the basis of the energy storage UP development principle and according to the provided energy storage control strategy. The results show that an energy storage system has an obvious effect for improving the system frequency, and the effect is better along with the improvement of the charging / discharging power of the energy storage system.

Description

technical field [0001] The invention relates to a PSASP / UPI-based energy storage system configuration method for high wind power penetration power grid frequency modulation requirements, which belongs to the technical field of wind power. Background technique [0002] The integration of large-scale wind power and other renewable energy into the power system is an important measure to achieve sustainable development, cope with climate warming, and implement energy-saving and emission-reduction policies. Since my country's wind energy resources are mainly distributed in areas with relatively weak power grids such as the Northwest and Northeast, far away from load centers, large-scale networking and long-distance power transmission are effective ways to achieve a high proportion of wind power grid-connected. As of the end of 2014, my country's cumulative installed wind power capacity has reached 114,609MW, and the momentum of development is still rapid. According to industry ex...
