PV UP-SCALE addresses important grid issues: technical impacts of PV inverters, interconnection guidelines, network risks, and required inputs to network planning.
The main questions to be answered are among others:
* What are the experiences of utilities with distributed (PV) systems ?
* Which are the experiences of clients with utilities ?
* Do hazardous voltage levels occur at the customer’s premises ?
* Do PV inverters introduce harmonic distortions which deteriorate grid quality ?
* Do large number of inverters in close vicinity disturb each other ?
* Do inverters affect utilities remote control signalling ?
Key tasks are presented in the following subtask list :
ST 4.1 : Review publications on impact of dispersed generation (download report)
ST 4.2 : Collect and evaluate experience with PV interactions from electricity companies (download report)
ST 4.3 : Completion of information by measurements in Low Voltage (LV) electricity networks (download report)
ST 4.4 : Review, comment and influence standards and rules for network interconnection (download report)
ST 4.5 : Assessment lessons-learnt and reporting (download voltage drop calculation software)
