Beijing Energy Micro-Electric Network

What is a micro-energy network?

Within the coverage of a micro-energy network, through the energy dispatch center, various distributed clean energy sources, various loads, energy storage devices, energy coupling elements, 5G communication base stations and other equipment are closely connected.

What is the energy system model for Beijing?

The energy system model for Beijing is developed with an open-source MESSAGEix modelling framework, which has been widely used for strategic energy planning and integrated assessment of energy-engineering-economy-environment systems (IIASA Energy Programme 2020; Krey et al. 2020).

What is a micro-energy grid?

The micro-energy grid originates from the concept of “micro-grid”, and in the future, it can realize energy interconnection in various regions of the world. On the basis of “microgrid”, micro-energy grid coordinates the interconnection of various energy sources such as heat energy, cold energy, and natural gas.

Why is it important to classify a micro-energy network?

Because of the variety of flexible loads, it is necessary to classify them for more reasonable control and scheduling. Micro-energy network includes various energy sources such as electricity, cold and heat, and many energy coupling devices.

How is Beijing's electric power system based on a Jing-Jin-Tang grid?

Considering the high proportion of imported electricity in Beijing's energy mix, the hourly simulation of the electric power system was based on the Jing-Jin-Tang (JJT) grid, covering Beijing, Tianjin, and northern Hebei, with a detailed description presented in the SI Appendix.

Where does Beijing's electricity come from?

Electricity consumption in Beijing depends on three main sources: local generation, imports from Inner Mongolia and imports from Shanxi province . Beijing's electricity self-sufficiency rate was less than 50% during the study period.
