Embodiment Construction

[0039] The energy storage monitoring system provided by the present invention, as a supporting part of the wind storage joint adjustment system, its main function is to collect various data sent by the energy storage system to key equipment (PCS), battery management system (BMS), protection device It stores and processes data, provides a manual control interface for energy storage equipment, and has advanced applications such as smoothing fluctuations, tracking plans, and reactive power control.

[0040] The ultimate control goal of the energy storage monitoring system's functions of smoothing fluctuations and reactive power control is the export active / reactive power of the entire wind storage system, and it needs to read the active / reactive power data of the wind power system during the control process, so the energy storage How does the monitoring system affect the wind-storage joint adjustment system? figure 1 The data shown depends on:

[0041] To stabilize fluctuations,...

Abstract

The invention relates to an energy storage monitoring system comprising a real-time operation system, an electric energy charge system, and a safe WEB issue system which are communicated with a network data transmission platform. The real-time operation system is located in a first safety area and acquires and processes data correlative with an energy storage system. The electric energy charge system is located in a second safety area and performs power grid application analysis and electric energy acquisition statistic. A firewall is arranged between the first safety area and the second safety area. The safe WEB issue system is located in a management information area and issues information to external units. A forward-power-dedicated safe physical isolation device is arranged between the management information area and the first safety area. The energy storage monitoring system uses a layered, distributed, and open network framework, and achieves combined monitoring of a wind power plant and an energy storage power station.

Description

technical field [0001] The invention relates to the field of electric power, in particular to an energy storage monitoring system. Background technique [0002] By combining the respective advantages of wind farms and battery energy storage systems, the wind-storage-integrated dispatching system can fluctuate the output power of wind farms as the distribution of wind energy inside the wind farm changes. Generally, the components of the output power of wind farms with frequencies above 0.01 Hz have a greater impact on the power grid. Installing an energy storage device on the low-voltage side of the step-up transformer in a wind farm can eliminate the power fluctuation component above 0.01 Hz, thereby effectively smoothing the power output of the wind farm and improving the grid-connected operation performance of the wind farm. [0003] The control idea of ​​the battery energy storage system is to quickly handle the high-frequency fluctuation components in the output active ...
