Energy storage for LV grid support in Australia

Energy Storage has always been an attractive proposition for utilities. In fact, having more flexibility in managing demand and supply of electricity can help to improve the operational stability and efficiency of the power system which is an objective of both electricity industry and governments. Energy Storage has the capability of being the mediator between demand and supply and its adoption would increase the flexibility of the electricity supply system. In particular, on the Low Voltage side, DNSPs could benefit from having distributed storage in particular points on the grid. Storage could take the form of new systems or use spent EV batteries with enough capability for grid-connected stationary applications. There are a range of different benefits that can be harvested by different actors in the electricity value chain, which makes the task of identifying the value proposition for Energy Storage in LV systems a rather complex one. The Energy Storage device can be owned and/or operated by one of the identified actors. Whichever ownership and control method is chosen, there are important challenges in the creation of market rules for appropriate valuation of the benefits from distributed storage. Suggestions for more research are given.
