How much is the ripple control of the energy storage inverter

What is a ripple control receiver (RCR)?

Definition Ripple control receiver (RCR) is an interface between a PV system and power grid company that enables the grid operator to reduce the feed-in power if necessary. Generally, if the grid is overloaded, the utility company will specify whether the PV system should reduce their feed-in power to 0%, 30%, 60% of their rated power.

How does a 3-phase hybrid PV inverter reduce power?

Fig.8. When a signal for power reduction will come from the Ripple Control Receiver, both the 3-phase Hybrid and the other PV inverter will reduce the power by the amount required. So, for example if there is a requirement for 60% power, both inverters will reduce their feed-in power to 60% of the nominal power.

Why should I integrate a ripple control receiver with a hybrid inverter?

By integrating the Ripple Control Receiver to the 3-phase hybrid inverter we can help balance the overall electricity demand and generation contributing to grid stability. Pay attention that, the Ripple Control setup is valid under the condition that grid code is set as 'Germany' for the inverter.

What are ripple control objects?

Control Objects In a ripple control system loads with the same physical characteristics are combined to one control object. For example: as many 6 hour geysers with the same ripple control commands are attributed until the installed power of these geysers amounts to about 1% to 3% of the target value.

Will load management with ripple control technology pay off?

Therefore, making use of load management with ripple control technology in order to reduce peaks will pay off within a few years. Expanding the distribution network is a permanent task, causing investments that need to be considered (interests, write-offs).

How does a ripple control system work?

The ripple control system sends the corresponding ripple control commands to the ripple control receivers which turn the loads on respectively off. For the load regulator it needs to be considered that it takes time (dead time) to transfer the ripple control commands and that the amount of ripple control transmissions per time unit is limited.
