ECgrid

Grid services and aggregator integration for BESS and microgrids

Flexible platform for frequency ancillary services and market aggregator connectivity

Overview

ECgrid

Description

The ECgrid from ENcombi, in conjunction with an ECpvX, offers the capability to provide frequency ancillary services AFRR and mFRR as well as FRR, FCR-N and FCR-D for the nordic synchronous area and FCR for the Central Europe synchronous area.

Market bidding activities are managed through a third party Virtual Power Plant (VPP) platform and are not within the scope of the ECgrid. Instead, the ECgrid interacts online with the VPP aggregator to receive won bids. This setup allows users of the ECgrid to work with various aggregators, as it is not tied to any specific one.

The ECgrid utilizes a power meter with Modbus communication capabilty to measure grid frequency. Based on these frequency readings, it will conduct the ancillary services and pass forward the associated power commands to the ECpvX controller.

The ECpvX serves as the primary device managing power flow to and from the battery. Through Modbus communication, it regulates both the active and reactive power.

Equipped with diverse control funcionalities including zero-export and spot-price arbitrage, the ECpvX receives control references from the ECgrid and adjusts battery operations accordingly. Addtionally, the ECpvX executes essential control functions such as LFSM-O/LSFM-U to adhere to various grid interconnection standards. For comprehensive details on the ECpvX, please refer to the ECpvX product page.

Product FAQ

ECgrid

ECgrid questions

My aggregator isn't on the list. Can it still work?

Possibly. Contact us about getting your aggregator added.

How is ECgrid wired into the site?

It reads grid frequency from a power meter over Modbus RTU, sends power commands to the ECpvX over Modbus TCP, and talks to the aggregator's VPP over HTTP.

How do aFRR and mFRR commands reach it?

Via Modbus, online via ECapi, or both. For commands via ECapi, the API setting must be enabled as well.

How do I set which grid area the site is in?

In the settings, choose the Central Europe synchronous area (DK1 and south) or the Nordic synchronous area (DK2 and north).

What happens to the battery's charge between activations?

When no ancillary service is ongoing, ECgrid brings the state of charge back to a target value, at a charge or discharge power you set.

Can it help us pass prequalification?

Yes. The built-in pre-qualification director runs several tests in sequence without changing settings in between. Before each test it presets the frequency, then waits 10 seconds.

In simulation mode you can also manipulate the grid frequency independently of the mains meter reading; a working mains meter connection is still required.

What are the hardware specs?

A DIN rail unit of 107 × 22.5 × 119 mm (H × W × D), weighing about 200 g.

It runs on 24 VDC ±15% (250 mA max) and operates from −20 °C to +70 °C. It has 1 × Ethernet and 2 × isolated RS485 ports, and an 8 GB industrial-grade SD card is included.

These answers are general information based on our product documentation at the time of writing. They are not binding and may change at any time. For your project, the current datasheet, manual and our written order confirmation apply.
