Virtual Power Plant

What is Virtual Power Plant?

In simple terms, the power generation plant will have a cloud-based data control center that aggregate production data from various distributed energy resources (DERs). The data center may use various communication technologies and internet of things (IoT) sensors to gather data, which allows an operator to monitor and control the production of each plant. By integrating several types of power sources such as solar, wind, small hydro and batteries, virtual power plants enable a reliable power supply. It also allows utilities to generate electricity using renewable energy sources, store it in battery banks and then supply it to customers.

What is Teiszmann Buffer Battery System (BBS)?

Energy Storage System (EES) is being used to store superfluous energy produced from alternative energy sources that can be used for to support the grid and help to avoid black outs , in the case of excess energy needed or by problems with the power generating plant.

Teiszmann BBS is having the benefits and applications as Energy Storage System (ESS) has and also has more than EES does have. Teiszmann Technology allows having a smart system of renewable generation and energy storage controlled via a dedicated IoT (Internet-of-Things) cloud network and big-data analytics platform in order to have a perfect “Virtual Power Plant”.

One of the main functions of Teiszmann BBS is to serve as an Energy storage which will make an important contribution to the stability of future power grids which have a significant share of renewable energy. It will become more important as the renewable energy share will get larger in the future energy mix.

What are the benefits and applications of Teiszmann BBS?

Integrating Buffer Battery System (BBS) with solar PV can make solar power dispatch able, reduce stress on the grid and optimize overall system resources.

Some of the key applications of BBS for solar PV integration are:

* Potential replacement/ reduction of diesel generators (DG) for backup power

* Peak shaving and load shifting

* Managing grid power quality

* Development of microgrids

* Demand response (DR) applications

The benefits of our technology beyond the integration of renewables;

Due the short-term variability and low predictability inherent to renewable sources, the solar- and wind-based generation capacities in electrical power networks soar, operators are finding it increasingly difficult to maintain grid stability and reliability. Teiszmann BBS can address these issues and thus provide an important contribution to the evolution of the electrical power grid.

Teiszmann BBS help to maintain grid stability and ensure reliable and high-quality energy supplies with having the below main applications and benefits;

* Permanent frequency regulation

* Effective spinning reserve

* Load levelling

* Peak shaving

* Power quality

* Capacity firming

Permanent Frequency Regulation

The necessity to meet the connection requirements forces the power generation plant to participate in the grid frequency and voltage regulation. Frequency regulation must be accomplished using storage systems, since the power source is not available at all time. For frequency regulation applications, the BBS is charged or discharged in response to an increase or decrease, respectively, in grid frequency caused by a sudden misalignment of energy supply and demand.

Effective spinning reserve

The BBS is maintained at a level of charge ready to respond to a generation or transmission outage. The system can respond within milliseconds to supply power to maintain network continuity while the backup generator is started and brought online.

Load levelling

This usually involves storing power during periods of light loading on the system and delivering it during periods of high demand. To describe in simple words, Teiszmann BBS can be used to store over capacity produced from alternative energy sources and sell them to a high price at peak times.

Peak Shaving

Battery storage systems primarily serve to cover peak load and in networks with insufficient control power and the grid stabilization. With BBS integration, the fluctuation in the grid can be reduced and peaks can be absorbed.

Power Quality

A BBS may help to protect downstream loads against short-duration events that affect the quality of the power delivered. The power quality issues can lead to brownouts and possibly a complete power interruption. BBSs can provide instantaneous voltage support by injecting or absorbing both active and reactive power.

In addition to voltage support, the BBS may serve as an uninterruptible power supply (UPS) that can bridge unplanned disruptions in service thus further enhancing the quality of power supplied to the energy consumers.

Capacity Firming

The BBS smooths the committed output and controls the ramp rate (MW/min) to eliminate rapid voltage and power swings on the electrical grid
