1 Introduction. Integration of renewable energy sources and distributed generation into the microgrid or smart grid is getting more and more attention because of the environmental concerns and electric utility deregulation [1-8].However, there are many technical challenges that should be settled for the successful grid integration of renewable energy sources.
The highly flexible and dispersed nature of grid connections in distributed PV power generation necessitates a reconsideration of the unified pricing method established in 2011. Given the variations in sunlight duration across regions, PV power pricing should be adjusted based on the scarcity of light resources, while also considering the data provided by IoT systems.
The research on grid-connected PVB systems originates from the off-grid hybrid renewable energy system study, however, the addition of power grid and consideration adds complexity to the distributed renewable energy system and the effect of flexibility methods such as energy storage systems, controllable load and forecast-based control is emphasized.

DG is regarded to be a promising solution for addressing the global energy challenges. DG systems or distributed energy systems (DES) offer several advantages over centralized energy systems. DESs are highly supported by the global renewable energy drive as most DESs especially in off-grid applications are renewables-based.
Distributed energy systems are an integral part of the sustainable energy transition. DES avoid/minimize transmission and distribution setup, thus saving on cost and losses. DES can be typically classified into three categories: grid connectivity, application-level, and load type.
