Energy storage master and slave control

What is a slave in the energy storage game?

The slave in the renewable energy game aims to minimize the operation cost of renewable energy while considering penalties for wind and PV curtailment. The slave in the energy storage game focuses on optimizing energy storage regulation performance and considers overcharge/discharge risks.

What is a master-slave game optimization model?

A master-slave game optimization model among multi-masters in the microgrid is established. The master-slave game optimization model selects the microgrid system as the game master and the renewable energy, energy storage and flexible load as the game slave.

How to measure the regulation margin of an energy storage slave?

When the SOC of the energy storage slave is 0.5, its charge/discharge regulation margin is the largest. Therefore, set the deviation cost to measure the regulation margin of the energy storage slave.

What is the difference between a master and a slave inverter?

The dispatchable power source, i.e. the energy storage (ES) unit, istreated as the master and the other non-dispatchable power sources, i.e. thewind and solar power units, are deemed as slaves. Correspondingly, the inverterconnected between the ES and the microgrid AC bus is defined as master inverterand the others slave inverters.

How DG inverters work in a master-slave microgrid?

In a master–slave microgrid, all the DG inverters are working in P / Q control mode when it is connected to theutility grid. However, when it is islanded, the master inverter has to switch to v / f control mode to provide voltage andfrequency references to the P / Q -controlled slaveinverters.

Can a master-slave game optimize microgrid/power systems under multi-master coexistence mode?

The optimization method based on master-slave game can provide a feasible optimization technical route for potential microgrid/power systems under the multi-master coexistence mode in the future.
