Facilitating Network Integration of
Distributed Solar PV
Addressing the characterisation of photovoltaic ( PV ) generation variability to help network operators appropriately plan for high distributed PV penetration . A method for estimating the amount a low-voltage feeder can accommodate without exceeding upper voltage limits has been developed , as well as methods to manage distribution voltage levels . Whilst the electricity grid can accommodate distributed PV generation , at higher penetration levels , we address two key impacts – voltage variability and voltage rise – contributing to the successful technical integration of distributed PV generation . |
Competitive Advantage • Comprehensive characterisation to describe the behaviour of PV generation variability throughout the day and year
• Creation of a simple and efficient method for estimating the level of PV generation a low-voltage feeder can accommodate , without exceeding upper voltage limits
• Expertise in methods for integrating PV systems , controllable loads and other devices , such as electrical storage , to manage distribution voltage levels
Impact • Simple and efficient methods for estimating maximum distributed generation capacity of a feeder that doesn ’ t require new communication infrastructure – shown to be more efficient and equitable than similar current proposed methods
• A tool in which network and microgrid operators can quickly and easily determine approximate values of maximum PV generation for their distribution feeders
