6 FAQs about [Southern Power Grid Micro-learning]

Can deep reinforcement learning be used in a microgrid with shared energy storage?

For the microgrid with shared energy storage, a new frequency regulation method based on deep reinforcement learning (DRL) is proposed to cope with the uncertainty of source load, which considers both frequency performance and the operational economy of the microgrid.

Is a multi-timescale coordinated operation method for microgrids based on deep reinforcement learning?

This paper develops a multi-timescale coordinated operation method for microgrids based on modern deep reinforcement learning. Considering the complementary characteristics of different storage devices, the proposed approach achieves multi-timescale coordination of battery and supercapacitor by introducing a hierarchical two-stage dispatch model.

How do energy storage systems work in a microgrid?

In an energy management strategy, the energy storage system plays a key role in compensating for power mismatch. Many kinds of storage devices can be used as an ESS in a microgrid, such as supercapacitors, batteries, and fuel cells. Power density and energy density are the two main metrics for selecting the proper devices.

What is microgrid energy management?

It is defined as a small cluster of distributed generators (DGs) and energy storage systems (ESS). These can operate in grid-connected or isolated modes [ 1 ]. Energy management is usually designed for microgrid operation to improve energy efficiency and minimize the operational cost [ 2 ].

How much power does a microgrid use?

PES for both microgrid area 2 and sES is 250kW/500kWh. The reference power is 4MW. The sES consists of VES and PES. The sES only provides frequency support for the microgrid area 1 to verify the impact of sES on frequency regulation. Fig. 4. The multi-microgrid structure with sES.

What is a microgrid?

The microgrid is considered a promising self-sufficient energy system to incorporate renewable energy sources (RES) into the main grid. It is defined as a small cluster of distributed generators (DGs) and energy storage systems (ESS). These can operate in grid-connected or isolated modes [ 1 ].
