A resilient distributed secondary control strategy is proposed for DC microgrids (MGs) with denial-of-service (DoS) attacks on communication channels to achieve accurate current sharing and voltage regulation.
In the islanded mode operation of a microgrid, a part of the distributed network becomes electrically separated from the main grid, while loads are supported by local DERs. Such DERs are typically power electronic based, making the full system complex to study.
The BMS modules enable control of up to 16 battery strings. Complex system designs are hierarchically scaled and include BMS MASTER and BMS SLAVE modules, where BMS SLAVE modules exchanges data with the BMS MASTER module via built-in CAN communication.
In a grid connected mode, the objective of microgrid operation is to maximize renewable power and enable participation in behind-the-meter (BTM) applications such as peak shaving, energy arbitrage, and ancillary services. Such an operation results in reduction of electricity.
Peer-to-peer mode is a control strategy based on ideas of "plug-and-play" and "peer-to-peer" used in power electronic technologies. In this mode, all DGs in the microgrid are equal and there is no master or slave DG.
Since microgrids are made up of several components that can function in network distribution mode using AC, DC, and hybrid systems, an appropriate control strategy and monitoring system is necessary to ensure that the power from microgrids is delivered to sensitive loads and.
