• We proposed a simplified but effective equvalencing method for large PV plants.
• Methodology aimed at supporting the bidding and pre-desing phase of PV plant erection.
• Methodology to verify the compliancy with system operators grid code requirements.
This paper proposes a methodology for the equivalent modeling of large photovoltaic power plants at the Point of Interconnection with the transmission/distribution network. The interest in such a methodology lays in the fact that recently Transmission/Distribution System Operators (TSOs/DSOs) have extended the requirements for the connection of renewable generation to their electricity networks beyond the only supply of active power, requiring ancillary services too. It is then a primary necessity for the Companies which operate in the market of large photovoltaic plants to have a simple but effective tool to verify the compliance of a proposed plant layout with specific TSO requirements (which vary from country to country) in order to support the bidding and preliminary design phase of the project.After an overview of the typical layout of large photovoltaic plants, the proposed methodology is fully described. In order to verify its reliability, the method is validated against exact load flow calculations on a test case photovoltaic plant layout. In the light of the good results achieved by the methodology validation, the last part of the paper proposes an application to infer the power plant capability and the compliance check with reference to specific TSOs requirements.
