Efficient management of distributed energy resources (DERs) is a vital aspect of power converter control in grid-connected systems. In order to ensure stable and reliable operations, fast and standardized information exchanges are necessary in smart grids. This study proposes an optimal distributed energy resource management system (DERMS) for a smart grid, which is connected to photovoltaics, battery energy storage, and an electric vehicle aggregator. The proposed management system comprises a communication architecture that facilitates the exchange of information between the individual control of the distributed generators and the master supervisory control algorithm. The proposed system is implemented on a real-time platform built using Typhoon HIL devices. A control strategy for energy management is developed, and the system is validated with the grid by integrating scenarios that stimulate different behaviors of the grid triggered by the DERMS under various circumstances. The IEC61850 communication standard is used as the communication standard to exchanges information and send commands to actuators between derms and grid and betwwn IEDs and grid.This paper explicitly examines the behavior of DERMS in a case scenario of shadowing the PV and the reaction of the control system to this unpredicted event in real-time, leading to the shedding of load from the grid and the management of setpoints after shedding. In this way, the control system developed here can operate within the predefined limits of the injected power from the network into the grid. Overall, this work contributes to the development of optimal management systems for DERs in smart grids, which are crucial for the effective integration of renewable energy sources into the grid.

Abstract
Efficient management of distributed energy resources (DERs) is a vital aspect of power converter control in grid-connected systems. In order to ensure stable and reliable operations, fast and standardized information exchanges are necessary in smart grids. This study proposes an optimal distributed energy resource management system (DERMS) for a smart grid, which is connected to photovoltaics, battery energy storage, and an electric vehicle aggregator. The proposed management system comprises a communication architecture that facilitates the exchange of information between the individual control of the distributed generators and the master supervisory control algorithm. The proposed system is implemented on a real-time platform built using Typhoon HIL devices. A control strategy for energy management is developed, and the system is validated with the grid by integrating scenarios that stimulate different behaviors of the grid triggered by the DERMS under various circumstances. The IEC61850 communication standard is used as the communication standard to exchanges information and send commands to actuators between derms and grid and betwwn IEDs and grid.This paper explicitly examines the behavior of DERMS in a case scenario of shadowing the PV and the reaction of the control system to this unpredicted event in real-time, leading to the shedding of load from the grid and the management of setpoints after shedding. In this way, the control system developed here can operate within the predefined limits of the injected power from the network into the grid. Overall, this work contributes to the development of optimal management systems for DERs in smart grids, which are crucial for the effective integration of renewable energy sources into the grid.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
