Large PV and battery penetration can largely reduce the customers’ cost while maintaining the voltage level. The increasing share of renewable energy sources (RESs) in electricity generation leads to increased uncertainty of generation, frequency and voltage regulation as well as difficulties in energy management.
We assume the customers having PV systems may install batteries, but those with batteries must have PV systems. Except for Case0 in which customers do not have any PV (nor battery), the penetration level of PVs and batteries over Case1, Case2, and Case3 is increasing.
A virtual power plant (VPP), as a combination of dispersed generator units, controllable load and energy storage system (ESS), provides an efficient solution for energy management and scheduling, so as to reduce the cost and network impact caused by the load spikes.
In BESS used for VPP, often the cost of the battery is high 1 and in many occasions it is used in combination with PV systems , . In this study, customers with battery must have a PV. Also, the solar feed-in tariff in Australia is declining fast. Soon, there will be no feed-in tariff during peak solar periods.
