This paper discusses three different techniques which can be used for power sharing control and adjustment among parallel converter-interfaced distributed energy resources in an autonomous microgrid. This ratio is decided by the distribution network tertiary controller and passed by the microgrid central controller to the primary controllers of each energy resource. In this paper limitations of the first two methods are discussed in detail and the proposed (third) method is designed such that it overcomes the limitations of the other two methods. The studies and discussions are validated for an autonomous microgrid under consideration through PSCAD/EMTDC-based simulations studies.
