ENERGY STORAGE APPLICATIONS

RENEWABLE INTEGRATION

UTILITY CURTAILMENT RECOVERY

Freemaq DC/DC series are able to store energy during periods of low demand from the grid, in order to later supply this energy when there is a higher demand. This has the bene-fit of selling the energy at a higher market price during peak periods. It also allows grid operators to supply electricity with a higher renewable origin. Since PV generation may not be at the same time as peak demand, this facilitates the flexibility and integration of renewable generation into the grid.

The Freemaq DC/DC series attenuates the intermittent nature of renewable energy sources, to provide a smoother power output. The Freemaq DC/DC controls the ramp rate at which power is injected into the grid, and thus reduces the impact of rapid power fluctuations due to sudden or transient conditions experienced by the PV array.

The system monitors the PV inverter output to inject or consume power accordingly to ensure the output remains within the ramp requirements.

Utility scale inverter production can be curtailed by the grid operator, due to the high energy sources penetration in the grid during certain periods. With this DC-coupled energy storage system, the excess energy from the PV field can be stored in the Battery Energy Storage System (BESS) and then delivered when needed.

CLIPPING RECOVERY

FREQUENCY REGULATION SYSTEM

PEAK POWER SHAVING

The Power Electronics Freemaq DC/DC gets the maximum revenues from the PV generator, by charging the battery storage system when the PV inverter is clipping the output power, due to the high DC/AC power ratios. This stored energy can be exported to the utility grid when the price per KWh is high.

Freemaq DC/DC provides ability to regulate grid frequency in both directions. When there is a grid overfrequency (generation>demand) inverter power output is curtailed and this energy is stored through charging batteries. When there is a grid under-frequency (generation<demand) inverter power output is increased by discharging the batteries and injecting more power to the grid.

By delivering stored energy to the grid during periods of high demand, it reduces the burden on the distribution network and increases significantly its efficiency. Energy is stored during periods of low demand increasing the load on the grid. During peak periods this stored energy is then injected into the grid reducing the demand at this time. The result is a more flattened demand curve which means the grid can avoid switching on more expensive and polluting generators.

THE INNOVATIVE MEDIUM VOLTAGE CENTRAL STRING BATTERY INVERTER

UTILITY SCALE MV BATTERY INVERTER

The Power Electronics PCSM medium voltage battery inverter is designed for utility scale storage applications, that require the advantages of a central inverter solution but also the modularity of a string architecture. The PCSM can reach up to a nominal power of 3.6 MVA and it is compatible with all battery technology and manufacturers. It also has the added advantage of having an integrated medium voltage transformer and switchgear.

The MULTI PCSM can support two or three independent battery systems and optimize the storage facility.

Power Electronics converters have been designed to be the lowest LCOE solution in the market for storage applications. The Power Electronics Freemaq PCSM offers proven hardwa-re to meet storage and grid support challenges.The energy production industry is embracing renewable energy sources. However, high penetration creates power transmission instability challenges, thus Grid Operators require stringent dynamic and static grid support features for solar inverters and Power Conversion Systems (PCS).

The converters can perform grid support functions such as: Peak Shaving, Ramp Rate Control, Frequency Regulation, Load Leveling and Voltage Regulation, controlled by a Power Plant Controller or SCADA. The Freemaq PCSM stations are turn-key solutions ready for connection to the battery contai-ner and MV power distribution wiring. Units are designed for concrete pads or piers.

Freemaq PCSK firmware includes the latest utility interactive features (LVRT, OVRT, FRS, FRT, Anti-islanding, active and reactive power curtailment…), and can be configured to meet specific utility requirements.

Frequency Ride Through (FRT). Freesun solar inverters have flexible frequency

protection settings and can be easily adjusted to comply with future requirements.

Anti-islanding. This protection combines passive and active detection

methods that eliminate nuisance tripping and allow to comply with the IEC

62116 and IEEE 1547 standards.

Frequency Regulation System (FRS). Frequency droop algorithm curtails the

active power along a preset characteristic curve supporting grid stabilization.

Q(V) curve. It is a dynamic voltage control function which provides reactive power in order to maintain the voltage as close as possible to its nominal value.

Low Voltage Ride Through (LVRT or ZVRT). Inverters can withstand any

voltage dip or profile required by the local utility. In this situation, the inverter

can inject current up to the nominal value.

Freemaq PCSK series are able to store energy during periods of low demand from the grid, in order to later supply this energy when there is a higher demand. This has the benefit of selling the energy at a higher market price during peak periods. It also allows grid operators to supply electricity with a higher renewable origin. Since PV generation may not be at the same time as peak demand, this facilitates the flexibility and integration of renewable generation into the grid.

The Freemaq PCSK series attenuates the intermittent nature of renewable energy sources, to provide a smoother power output. The Freemaq PCSK controls the ramp rate at which power is injected into the grid, and thus reduces the impact of rapid power fluctuations due to sudden or transient conditions experienced by the PV array. The system monitors the PV inverter output to inject or consume power accordingly to ensure the output remains within the ramp requirements.

LOAD LEVELING


PEAK POWER SHAVING

By delivering stored energy to the grid during periods of high demand, it reduces the burden on the distribution network and increases significantly its efficiency. Energy is stored instead of injected into the grid during periods of low demand, which as a result increases the load on the grid. However, during peak periods this stored energy is then injected into the grid, which reduces the demand at this time. The result is a more flattened demand curve which means the grid can avoid switching on more expensive and polluting generators.

Freemaq PCSK series helps the integration of renewable sources, by helping to maintain grid stability and power quality. It can help support the grid voltage by generating capacitive or inductive current.Other features include Voltage Control, Reactive Power Control and Fault Ride Through Support.

GRID SUPPORT


Freemaq PCSK provides ability to regulate grid frequency in both directions. When there is a grid overfrequency (generation>demand) inverter power output is curtailed and this energy is stored through charging batteries. When there is a grid under-frequency (generation<demand) inverter power output is increased by discharging the batteries and injecting more power to the grid.
