Abstract
Today, smart grid is considered as an attractive technology for monitoring and management of grid connected renewable energy plants due to its flexibility, network architecture and communication between providers and consumers. Smart grid has been deployed with renewable energy resources to be securely connected to the grid. Indeed, this technology aims to complement the demand for power generation and distributed storage. For this reason, a system powered by a photovoltaic (PV) has been chosen as an interesting solution due to its competitive cost and technical structure. To achieve this goal, a realistic smart grid configuration design is presented and evaluated using a radial infrastructure. Three-voltage models are used to demonstrate the grid design. Smart Meters are included via a SCADA to acquire and monitor the electrical signal characteristics during the day and to evaluate it through a statistical report. An operational data center (ODC) is used to collect the SMs statistical report and to review the demand-offer (DO) powers balance. The obtained results with Matlab/Simulink are validated by the famous ETAP software.

Summary
The integration of renewable energy sources, such as photovoltaic systems (PVS) into the electrical power grid (either low or medium voltage) throws up several technical troubles like instability, energy quality degradation, signal parameter fluctuation (current, voltage and frequency) and the renowned phenomenon of mismatch between load supply and demand. Electricity grids are stable systems contrarily to renewable energy plants (PV and Wind) which are decentralized, unpredictable and their connection to the grid could lead to instability while coupling them. These phenomena limit the integration of renewable energies into conventional grids and harm their sustainability [1]-[2]. This work aims to study these problems and propose some appropriate solutions to optimize production, control connection and stability via flexible smart grid architecture. From the reviewed literature, earlier studies had proved that with the considerable integration, several drawbacks [3]-[7] concerning reliability of these systems appears to be real boundaries towards their integration
