“…The main function of the power management system (PMS) is to maintain an optimal operating point for the microgrid. PMS assigns the active and reactive power set points for the DG units to (i) properly share the real and reactive power among the DG units based on either a cost function associated with each DG unit or a market signal [23], (ii) appropriately respond to the microgrid disturbances and major changes [43], (iii) balance the microgrid power, and (iv) provide the resynchronization of the microgrid system with the main grid, if required [43]. The set points are then transmitted to the local voltage controllers of the DG units.…”

This paper focuses on the problem of voltage control of islanded inverterinterfaced microgrids consisting of several distributed generation (DG) units with parallel structure. The main objectives are to (i) design a decentralized/distributed voltage controller with minimum information exchange between DG units and their local controllers (ii) design a fixed-/low-order dynamic output feedback controller which ensures stability as well as desired performance of the microgrid system in spite of load parameter uncertainties. To this end, the problem is formulated as an optimization problem which is the minimization of the cardinality of a pattern matrix subject to an H ∞ performance constraint. Since the problem is intrinsically non-convex, a convex design procedure for the controller synthesis is proposed in this paper. The effectiveness of the proposed controller is evaluated through simulation studies and Hardware-In-the-Loop (HIL) verifications. The simulation and experimental results demonstrate that the effectiveness of the proposed control strategy.

Abstract-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.Index Terms--Microgrid, Distributed Energy Resource (DER), Power Sharing.

“…The concept of ac/dc MicroGrids (MGs) has been proposed in recent years to increase reliability, power quality, decrease losses and pollution in the distribution power systems [1], [2]. Furthermore, dc MGs are more applicable, reliable and efficient systems to integrate many power sources and loads, such as photovoltaic arrays, fuel cell units, battery storages, motor driven loads, and full converter based generators such as micro-turbines and wind turbines, which naturally have a dc coupling.…”
