Capacity of Virtual Energy Storage System for Frequency

Due to large thermal inertia of buildings and flexibility of interruptible loads, smart buildings pose a remarkable potential for developing virtual energy storage systems (VESSs). However, current literature lacks advanced models to quantify and thus properly optimize available capacity of VESS for power system ancillary services, especially frequency regulation services (FRS).

Time to take virtual power plants seriously

As society moves away from centralised fossil fuel generators to increasing shares of distributed renewable energy resources, the idea that customers'' homes could become host to virtual power plants (VPPs), joining the dots between electricity supply and demand across the grid, has gradually gathered traction. Andy Colthorpe speaks with Suleman Khan CEO of

''Virtual contract'' to double Neoen''s BESS capacity in Queensland

Neoen, AGL''s first virtual battery agreement. Readers of Energy-Storage.news will be aware that this is the second agreement the two companies signed, the first formalising in 2022. The initial agreement pertained to 70MW/140MWh power and energy from the 100MW/200MWh Capital Battery project located in the Australian Capital Territory (ACT).

Grid-Scale Virtual Energy Storage to Advance Renewable Energy

It is now widely recognized that energy storage enables increased integration of renewable resources. One of the uses of storage is to provide synthetic inertia, making up for some of the inertia lost from displaced conventional generation, thereby maintaining frequency stability. However, energy storage systems continue to be very expensive, and this motivates

Virtual Power Plant: A Growing Energy Storage Trend in 2025

The basis of a virtual power plant is that an electricity grid virtually connects hundreds, even thousands, of homes. These homes may already have solar and energy storage facilities installed. A virtual power plant can help use them collectively to act as a backup. It can be used when demand soars or to take excess power off the grid when needed.

Distributed real-time power management for virtual energy storage

As to virtual energy storage system (VESS), Cheng et al. investigated the benefits of VESS on frequency response [17], where VESS was composed of various traditional energy storage systems (electrochemical, mechanical, electrical and thermal energy storage system) and domestic flexible loads which had ability to participate in demand response.
