Integration of distributed renewable energy sources in microgrids presents many challenges to grid such as voltage, stability and power management issues. In literature different control strategies to improve the performance of microgrids integrated with renewable energy sources proposed. FACTS based controller such as Unified Power Flow Controller (UPFC) has also been employed in microgrids to improve the power management and transient stability. Coordinated control strategies between UPFC controller and DERs have been developed. However, the underlying communication for realizing these strategies has not been discussed. This paper presents IEC 61850 and XMPP based communication for coordinating UPFC and DERs in microgrid for its stable operation. IEC 61850 information model for UPFC controller is developed. Furthermore, the XMPP protocol is utilized to provide the scalability for communication network in microgrids with high penetration of DERs. Additionally, XMPP also provides improved security along with the scalability. IEC 61850 message exchanges over XMPP communication between different components of microgrid for power management is demonstrated.

The demand for high quality electricity and growing electricity consumption has been caused by increasing electrification of daily life causes and the rising number of sensitive or critical loads. Due to the rapid increase in global energy consumption and the diminishing of fossil fuels, the customer demand for new generation capacities and efficient energy production, delivery and utilization keeps rising. The micro grid concept has the potential to solve major problems arising from large penetration of distributed generation in distribution systems. A proper control strategy should be implemented for a successful operation of a micro grid. Different load models can be simulated and analyzed using MATLAB and PSCAD software. In this paper, the work done in the field of Micro Grid has been reviewed.

“…In [17]- [19], the methods of the congestion management optimizations, the line loss minimization and the differential evolution (DE) were integrated into the power flow models of UPFC, respectively. In [20]- [22], the power flow models of UPFC had taken certain additional parameters into account, such as the system parametric uncertainties, the wind power uncertainties and the prerequisites of micro-grids. Nevertheless, the above proposed advanced algorithms for power flow modeling of UPFC are based on many additional prerequisites, uncertainties, or objective functions.…”

The unified power flow controller (UPFC) is recognized as one of the most promising flexible ac transmission system (FACTS) devices for modern power systems, due to its versatile functionalities. Based on typical operation conditions, this paper investigates the global and local power flow operation rules of the UPFC embedded transmission system theoretically. First, the detailed global power flow model (GPFM) and the local power flow model (LPFM) are established concerning several selected critical points (SCPs) in the system. The theoretical power flow operation rules for the ranges, the movements and the trajectories of GPFM and LPFM are analyzed, respectively. Then, the case study is performed based on the proposed simplified model, and the results are analyzed from GPFM and LPFM perspectives respectively. The operation rules and the power flow ranges is studied. Further case studies based on the proposed original mathematical model are also carried out, and the results are listed from different viewpoints of two-dimensional planes and three-dimensional spaces. All types of results are also analyzed from GPFM and LPFM perspectives, which verify that the UPFC is adaptive to various operation conditions for power flow regulation. INDEX TERMS Unified power flow controller, global power flow model (GPFM), local power flow model (LPFM), power flow operation rules, typical operation conditions.
