What is a microgrid?

Microgrids are known as clusters of distributed energy resources (DERs) relying on integrated control systems to coordinate distributed generation including intermittent renewables, demand response and storage units [ 1 ]. Their development can be beneficial for a variety of players, investors and grid operators.

How does microgrid C work?

Due to the abundant wind and solar resources in the area, Microgrid C has a large installed capacity of wind turbines and PV systems. After meeting its own load demand, it transfers excess energy to the shared energy storage station. Throughout the day, Microgrid C primarily relies on the shared energy storage station for energy exchange.

Why should energy storage equipment be used in a multi-energy micro-grid system?

The introduction of energy storage equipment in the multi-energy micro-grid system is beneficial to the matching between the renewable energy output and the electrical and thermal load, and improve the system controllability , , .

How much energy storage capacity does a microgrid have?

The total capacity of individually configured energy storage systems for each microgrid is 106.49 + 140.30 + 193.375 = 440.165 kW, which is significantly higher than the capacity of the shared energy storage station at 366 kW.

Does microgrid B have a wind turbine capacity?

However, Microgrid B has a relatively mild wind resource, resulting in a wind turbine capacity of only 106.5 kW, which is nearly 100 kW less than its PV capacity. Figure 5 shows the power and energy storage profile of the shared energy storage system.

What is multi-objective optimization in multi-energy microgrid?

Multi-objective optimization model of comprehensive planning of multiple energy storage forms. Multiple energy storage devices in multi-energy microgrid are beneficial to smooth the fluctuation of renewable energy, improve the reliability of energy supply and energy economy.
