Embodiment 1

[0036] This embodiment is a method using intermittent energy consumption monitoring devices under the distribution network. The measurement and control unit conducts online monitoring of the on-site operating status of each monitoring unit and transmits it to the background server in real time. The background server combines the received real-time data with each constraint The conditions are compared with the data in the intelligent expert database, and the background server makes an adjustment decision based on the comparison result and transmits the adjustment decision to the measurement and control unit through the wireless communication network to adjust the control unit, including adjusting the switch station and changing the access distribution. The network topology of power supply and interruptible loads controls the operating status of distributed power sources and interruptible loads through the switching station. After adjustment, the measurement and control unit trans...

Embodiment 2

[0042] The difference between this embodiment and Embodiment 1 is that the adjustment decision in this embodiment includes controlling reactive and active power output of distributed power supply, active and reactive power output of energy storage equipment, interruptible load regulation, reactive power compensation regulation and OLTC tap position.

Embodiment 3

[0044] The difference between this embodiment and Embodiment 1 is that: the wireless communication network used in this embodiment is a 4G wireless communication network.

Abstract

The invention discloses a monitoring device for intermittent energy consumption under a distribution network and a monitoring method thereof. The combination of prediction and online monitoring effectively solves the problem of increased load peak-valley difference and power quality problems in the power grid after the intermittent energy is connected to the grid. problems such as deterioration and reduced operational stability.

Description

technical field [0001] The invention belongs to the field of electric power intelligent control systems, and in particular relates to a monitoring device for intermittent energy consumption under a distribution network and a monitoring method thereof. Background technique [0002] With the continuous growth of power demand, the deepening of the shortage of traditional energy sources, and the increasingly prominent environmental problems, the large-scale grid connection of distributed generation (DG) will become a challenge for power grid enterprises. The power generation of distributed generation (DG) is intermittent and Uncertainty, the traditional distribution network has been unable to meet the needs of intermittent energy systems composed of DG, energy storage systems, and controllable loads. [0003] The Active Distribution System (ADS) is a distribution network with the ability to combine and control various distributed energy sources. Investment in upgrading the powe...
