Load-Sharing Control Techniques for LV and MV Networks

The main objective of load-sharing is to distribute the active and reactive loads among the available DGs while maintaining voltage regulation and accommo­dating various types of loads [13]. In LV and MV networks, load-sharing becomes challenging due to the following factors.

• Most DGs have some local loads,

• Most DGs are non-dispatchable RESs, and

• The stability and reliability of the system gain importance, apart from the cost.

Three different methods of load sharing are commonly employed: droop-based control, communication-based control, and droop-based control with communi­cation link, as described in the following subsections.
