Teaser text

Addressing the characterisation of photovoltaic (PV) generation variability to help network operators to plan appropriately for high penetration of distributed PV. A method for estimating the amount a low-voltage feeder can accommodate without exceeding upper voltage limits has been developed, along with methods to manage distribution voltage levels.

Body Text

Competitive advantage

  • Comprehensive characterisation which describes the behaviour of PV generation variability over the course of the day and over the course of the year
  • The 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

Impact

  • Simple and efficient methods for estimating maximum distributed generation capacity of a feeder that require no new communication infrastructure and are shown to be more efficient and equitable than similar methods currently proposed
  • A tool through which network and microgrid operators can quickly and easily determine approximate values of maximum PV generation for their distribution feeders
  • An original distributed voltage control method using residential PV systems and controllable loads to ensure voltage levels, upper and lower, are maintained within regulation limits

Successful outcomes

  • Feeder modelling for distribution operators

Capabilities and facilities

  • Software tools to expedite analysis of feeder capability
  • Realtime digital simulation facilities to verify models
