Shanghai Jiading 202207 Abstract: A large proportion of the development of wind and solar power generation will have a fatal impact on the moment of inertia and standby required by the power grid, seriously threatening the smooth operation of the power grid, this article combines with the AcrelEMS enterprise microgrid system to talk about how enterprises respond
.
Keywords: orderly use of electricity Load regulation Integrated energy management Enterprise microgrid 0 Introduction Since September 2020, carbon peaking and carbon neutrality have become hot topics in the energy circle, and new energy sources such as wind and solar have been placed high hopes
.
[1]1 Background In energy planning, new energy sources such as wind and solar have been strongly supported and developed, and they must assume the role of the main power supply in the 30.
60 target; Coal production is restricted, and the scale of the coal-fired machine assembly machine must even be cut
.
Under the recent cold wave, the "pulling gate power rationing" in Hunan, Jiangxi and other places has confused both inside and outside the industry: new energy sources such as wind and solar cannot contribute in the frozen snow, inter-provincial transmission channels are difficult to take on a big responsibility, and governments at all levels are forced to coordinate various resources to promote coal production and transportation, ensure the full load operation of coal-fired power units, and cooperate with orderly electricity consumption schemes to ensure that people's livelihood is not affected
。 [2]2 In the future, a large number of new energy will be connected to the grid for power generation, and a unified power trading center will be built throughout the country, and the volatility and intermittent power supply of the power grid will cause large and rapid fluctuations in electricity prices, and the distribution and consumption systems of enterprises will need to be adjusted to meet the needs
of future development.
Different from the existing enterprise power distribution and consumption, the future enterprise will have a large probability of rooftop distributed photovoltaic power generation system, energy storage system as an electric energy storage pool, and adjustable load represented by charging piles, which will form a "source network charge storage and charging" enterprise microgrid system
together with the large power grid and the distribution network within the enterprise.

1 Overall Introduction AcrelEMS enterprise microgrid system collects data through high-performance edge computing gateway and uploads it to the enterprise microgrid platform
by installing monitoring, analysis, protection and governance devices at key nodes of source, network, load, storage and charging.
According to the grid price, electricity load, power grid dispatching instructions, etc.
, the platform adjusts the control strategy of each system and remotely issues it, so that the enterprise microgrid always operates efficiently and stably, reduces the cost of electricity for enterprises, and realizes energy interconnection and information interaction

1 main function power monitoring to achieve the power system of the five remote function, according to the scene situation of the page configuration drawing distribution primary figure monitoring, can achieve curve trend analysis, the power parameters of the collection, view the comprehensive protection SOE events, view the fault recording, the power parameters for maximum, very small, average statistics, the main equipment monitoring such as: DC screen, generator, transformer, etc
。 Electric energy management provides functions
such as electricity collection copying, electricity consumption statistics, time-phased electricity consumption statistics, electricity consumption year-on-year analysis, and grouped electricity consumption statistics.
Power quality provides steady-state monitoring of power quality, harmonic spectrogram analysis, curve analysis, SOE events, ITIC, SEMI tolerance curve analysis, fault recording and other functions
.
Energy consumption analysis provides branch energy consumption statistics, group energy consumption statistics, energy consumption discount statistics, energy consumption year-on-year analysis, energy flow map and other functions
.
Distributed PV provides functions such as photovoltaic power plant operation monitoring, inverter operation monitoring, power station power generation statistics, inverter power generation statistics, photovoltaic power station distribution monitoring, inverter curve analysis and so on
.
Archives and O&M provide equipment definition, equipment file management, equipment maintenance reports, equipment QR code maintenance and other functions
.
Provide task management, inspection records, defect records, police records, emergency repair records, notification work orders and other functions
.
4 Conclusion AcrelEMS enterprise microgrid system helps enterprise users to carry out centralized monitoring, unified scheduling and unified operation and maintenance of enterprise electricity consumption through a set of systems, and at the same time meet the requirements of
reliable, safe, economical, efficient and orderly use of enterprise electricity.
