Electrex - Flexibility From Renewables: Why Traditional Monitoring Is No Longer Enough

..  

The LIBRA CCI UPS  is a Power Plant Controller (PPC) / Central Controller (CCI) that not only complies with the new requirements of ARERA Resolution 385/2025, but also incorporates additional functionalities and unique features, making it a multifunctional and strategic device.

Libra CCI UPS: The System Engine

The core component of the device is the Class 0.2S Network Analyzer, which serves as the functional engine of the system. Compared to standard solutions, this precision enables:

  • Accurate analysis of network parameters up to the 51st harmonic

  • Advanced power quality monitoring

  • Possibility to monitor environmental parameters

  • Customized management of energy flows from generators and loads

  • Intelligent energy management and device integration

In addition to its role as a Power Plant Controller (PPC), the Libra CCI UPS is a programmable device, capable of extending its operational logic to manage the energy of the entire facility.

It allows:

  • Monitoring of photovoltaic production and other generators in the plant

  • Management of storage systems

  • Integration, monitoring, and control of third-party devices (heat pumps, industrial machinery, energy-intensive loads)

  • Optimization of self-consumption and load distribution

  • Centralized collection and processing of energy data and other field sensors

These capabilities, together with the flexibility to integrate multiple devices, make it not only a Power Plant Controller (PPC) CCI compliant with regulations but a true advanced energy control hub.

Operational Features of the System

The Libra CCI UPS integrates all functionalities required for Medium Voltage (MV) installations:

  • Transmission of production and exchange data at the network connection point to the DSO (PF1)

  • Remote control and power regulation (PF2)

  • Provision to execute dispatching services (PF3)

Hardware Architecture and Main Components

Main Components:

  • Plug & play CCI panel with quick connectors (no need to open for installation)

  • Class 0.2S Network Analyzer

  • Integrated backup battery for service continuity

  • Provision for EMS logic

Compatible Accessories:

  • Network analyzers for low voltage measurements

  • MV current/voltage transformers (class 0.5S)

  • I/O devices for state acquisition and disconnection commands for non-controllable inverters

  • Energy supervision and management software Energy Brain

Energy Brain: Advanced Energy Monitoring Platform

The Libra CCI UPS can be integrated with Energy Brain, a platform designed for complete control of energy flows.

The solution enables:

  • Real-time monitoring of production, consumption, and power quality

  • Remote access to data

  • Support for optimizing plant performance

Commissioning

The startup procedure of the Libra CCI UPS includes:

  • Installation verification and preliminary checks

  • Configuration of field devices

  • Configurations required by the DSO

  • Complete functional system tests

  • Configuration of cryptographic keys

Additional Services and Operational Management

The system is supported by a dedicated service package including:

  • Periodic security key updates

  • Passive system monitoring

  • Diagnostics of anomalies and malfunctions

  • Defined intervention times

  • Provision for future PF3 activation


The Electrex Libra CCI UPS PQ is a Power Plant Controller (PPC) central controller for photovoltaic plants above 100 kW in Medium Voltage, compliant with CEI 0-16 and PF1/PF2 requirements of ARERA Resolution 385/2025/R/EEL, with PF3 readiness.

  • Commissioning included

  • Management of multiple sections or inverters

  • Integrated backup battery

  • Plug & play panel connectors

It integrates a 12 Vdc backup battery ensuring operational continuity even in the absence of network power and coordinates plants with multiple sections or inverters.

The system incorporates a Class 0.2 network analyzer, enabling Power Quality evaluation according to EN 50160 and EN 61000-4-30, detecting harmonics and events such as spikes, sags, and interruptions.

The integrated web server allows real-time data visualization, chart generation, and reporting.

Communication is provided via Ethernet, RS485, and RS232, with the possibility to extend the network to additional Electrex devices, making the Libra CCI a master node for more complex supervision systems.

The unit also features a high-visibility display with joystick keyboard, 5 expandable digital inputs, 3 digital outputs, auxiliary analog outputs, dedicated protections, and preconfigured 4G/GPS antennas, extendable up to 10 meters.
