The paper proposes the integration of photovoltaics into distribution power system through inverter control and optimally managing the power flow based on smart energy meter data. The concept of Unbundled Smart Meter (USM) is used which to optimally integrate the inverter control logic with in the Smart meter which requires the construction of SMX (Smart Meter Extension) library. The proposed approach is adapted to make the design more robust and dynamic. State feedback controller has been designed to control the power flow to and from between the inverter and grid through USM and hence provide additional services to support grid operations. The proposed system gives the flexibility of adding numerous functionalities in the installed smart meter without the fuss of firmware change and hence integration of renewables to grid becomes more efficient as the meter’s instantaneous data are used in the dynamic control of the system. The validation of the proposed scheme is achieved by time domain simulations on MATLAB/Simulink R2018a platform along with Arduino programming on Proteus 8.1 software. These results are further assessed through Hardware experiment observations.

“…The implementation of the standard IEC TR 61850-90-7 was tested in the Department of Electrical Engineering of FCT NOVA. The micro grid present in the laboratory is composed of a meteorological station, an occupational monitoring system, power consumption equipment (standard and Unbundle Smart Meter (USM) [1]), energy production equipment (PV panels, wind turbine and hydrogen fuel cell) and energy storage equipment, as presented in Fig. 2.…”

“…However, with the increase of the number of DERs in the electric power system, it is necessary to create new and intelligent approaches to manage the network. A new concept of inverters, called smart inverters or advanced inverters, have demonstrated to be an important asset on network stability, improving distribution feed performance and integration of DERs, and manage the DERs to compensate for electrical anomalies rather than just disconnecting from the power grid [1].…”

Currently, there is a big correlation between the exponential technological development (verified in the last decades) and the increasing energy dependence in industrial and residential environments. A growing number of Distributed Energy Resources (DERs) led the utility operators to explore new methods of network planning and management. New approaches and concepts have emerged, such as the smart grid, showing exciting results in increasing the hosting capacity for DERs and Renewable Energy Sources (RES). Standardized automation, control, and communication systems have shown to be important keys to perform intelligent methods to manage energy efficiently. Smart inverters have proven to be a helpful tool in minimize adverse effects on the performance of electrical power system, so that the DERs can play an active role in supporting operations and remain connected during short-term voltage and frequency anomalies. This paper shows how to control and monitor an inverter using the IEC TR 61850-90-7 standard. A comparative analysis between the IEC TR 61850-90-7 and UL 1741 standards is presented. These standards are specific inverters standards, showing differences in performance and in the advantages of using them. The importance of smart inverters in the smart grid and its role is also discussed.

From the electrical point of view, the concept of smart community (SC) was defined as a distributed system consisting of a set of smart homes, distributed energy resources (DERs) and energy storage systems (ESSs) using SC controllers to enable smart power management. In this context, the SC energy management system (SCEMS) acts as aggregator of these resources, aiming to assure benefits for every SC stakeholder by setting the SC operation. The references given by the SCEMS must be accurately tracked by the energy routers (ERs), intended as one of the key components of the SC, acting as smart interface between the utility grid and the prosumers' DER and ESS. This study proposes a flexible, robust and simple control strategy for a single-phase ER. The ER regulates the active and reactive powers in grid-connected (GC) mode, and the voltage and frequency when operating in stand-alone (SA) mode. A seamless transition between SA and GC is demonstrated, avoiding undesired transients. The design and implementation of the proposed control strategy is progressively explained. Finally, this is tested via simulation (in PSCAD/EMTDC software) and verified with the experimental prototype.
