研究目的
Investigating the issues and challenges associated with the integration of solar photovoltaic systems (PVS) with the electric utility grid, focusing on power generation through grid-connected PVS.
研究成果
The PVS in integration with the electric utility grid is one of the most emerging tools in the field of DERs. The paper discusses important issues of PVS that affect the performance of the connected grid and highlights the challenges to overcome these issues. It suggests that power electronic devices, MPPT controllers, and energy storage devices could be employed to minimize the problems associated with variability and uncertainty in grid-integration. However, the involvement of PV inverters in the PVS also leads to challenging issues regarding harmonics. The paper concludes that developments in grid-connected PVS are still needed that incorporate technical and financial aspects to assess the balance of the electricity price for grid-connected PVS.
研究不足
The paper highlights the technical and application constraints of integrating PVS with the electric utility grid, such as high penetration level, variability and uncertainty in power generation, and the need for power electronic devices and energy storage systems to mitigate these issues. It also points out the lack of deep studies on how environmental effects affect the performance of the grid in grid-connected large scale PVS.
