6 FAQs about [Battery virtual power and system mismatch]

What is a virtual power plant (VPP)?

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.

Can a battery energy storage system be optimized for VPP applications?

This paper proposes a multi-objective optimization (MOO) of battery energy storage system (BESS) for VPP applications. A low-voltage (LV) network in Alice Springs (Northern Territory, Australia) is considered as the test network for this study.

How EV real-time charging price settings affect VPP energy scheduling?

The real-time EV electricity pricing strategy improves energy utilization efficiency and collaboratively ensures the stability of power system. The impact of EV real-time charging price settings on the VPP energy scheduling is significant.

Does PV & battery penetration affect network impact?

The results demonstrate that: Higher PV and battery penetration leads to less customers’ cost but higher network impact. In comparison to no PV or battery, all customers with PVs and batteries have more than 50% decrease in the total cost. The real network modeled in DIgSILENT PowerFactory has more complex behaviors than the simplified network.

Can a customer install a battery with a PV system?

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.

Why is large PV & battery penetration important?

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.
