The Australian National Electricity Market (NEM) has experienced a dramatic transformation due to the rapid uptake of both small and large-scale renewable energy generation, along with the closure of multiple coal power plants. The Australian state, South Australia, epitomises this transformation as the share of renewable energy generation in the state grew from 14% in 2009 to 47% in 2018, dominated by wind power. Combined with limited interstate transmission capacity, the state's power system has experienced instantaneous penetration from wind generation in excess of 120% - the highest for any major power system in the world. This high presence of non-synchronous generation reduces the system strength that has traditionally been provided by synchronous generators. The ESCRI-SA 30MW Battery Energy Storage System (BESS) installed on the lower Yorke Peninsula in 2018, near the end of a long 132kV single-circuit radial feeder, is a Grid Forming BESS built on ABB's Virtual Synchronous Generator platform, which strengthens the grid by providing inertia, high fault current and fast power injection, as well as competitive market services on the NEM. It is also capable of seamlessly transitioning into islanded operation when faults occur on the upstream feeder, thus ensuring continuity of supply to local customers by operating an islanded power system with the nearby 91 MW Wattle Point Wind Farm and distributed solar PV. ESCRI-SA addresses an array of challenges, and reinforces how BESS with Virtual Synchronous Generator technology, can provide multiple value streams to utilities, consumers and the broader electricity market, as well as enabling large scale power systems to operate at 100% renewable energy.
