The main goal of this project is to produce a "Utility/PV Interface Criteria". Other aims of the study are to generate information useful to both utility and PV designers on this specific area of interfacing.
Research is being carried out in order to produce a 'Utility Photovoltaic (PV) Interface Criteria'. When connecting PV plants to an electric network, several boundary conditions have to be kept in mind in order to avoid malfunctions of the existing grid and/or the PV plant. Investigations on the following issues has been performed: European standards, inverter type requirements, harmonic distortion propagation, voltage fluctuation and economic and institutional aspects.
When connecting PV plants to an electric network, several boundary conditions have to be kept in mind in order to avoid malfunctions of the existing grid and/or the PV plant. For this reason this project will analyze in depth the following areas:
1) Electric compatibility requirements (reactive energy demand, harmonic distortion...).
2) Safety related topics.
3) Load compatibility between the pv electricity generation and the distribution system.
4) Economic and institutional issues.
With this project useful information on the existing regulations will be generated related with the interconnection of the PV generators to an utility network (auto-producers, others). Summary of the problems experienced, obtained in this specific area of interfacing during the operation of the already existing PV plants (inverters, reactive energy demand, effects derived from the transformer, harmonic distortion effects, ...). Institutional and economics aspects and benefits derived not only from the energy produced but also related areas.
