FLEXIBLE AND SCALABLE ARCHITECTURE

Fractal EMS has a flexible and scalable architecture that allows ­­assets to be easily added, removed or changed. Dispatch one installation or your entire portfolio while reliably managing your fleet.

 

 

 

 

Fractal EMS provides system integration and control, active management and monitoring, P/Q response capability and user interfaces to monitor system conditions, safety controls and faults/alarms. Fractal EMS is size and technology agnostic.

FRACTAL EMS CONTROL MODES

Manual Schedule

Schedule pre-programmed and customizable applications (stack up to ten) through the Fractal EMS Calendar.

Monitor and Respond

Fractal EMS monitors load, pricing, or SCADA (AGC) and responds with predefined applications.

Measure and Respond

Fractal EMS measures frequency, current, and voltage (and calculates power), and responds with predefined applications.

Receive and Respond

Fractal EMS receives commands via SCADA (AGC) or receives commands from a third-party via API.

COMMUNICATION & CONTROL SCHEMES

Fractal EMS can configure communications and network security to meet your specific project needs.

Cloud Dispatch

Schedule dispatches through the Fractal Calendar. Also receive API commands, ADS (CAISO) or Dispatch Calendar invites from Fractal Model

Utility SCADA Dispatch

Securely receive power (P/Q) commands from SCADA (all data points securely sent to the cloud for monitoring, reporting and predictive failures).

Local Dispatch

The Fractal Site Controller can be programmed to respond autonomously by responding to local measurements (voltage, frequency, load, etc.)

SECURE COMMUNICATIONS

  • Secure (e.g. 2-factor security authentication) access and communications, using industry standard protocols, including TLS 1.2, Modbus/TCP and DNP 3.0
  • Supports multiple communication protocols: RESTful Web API, Modbus, DNP3, IEC61850, IEC60870-5-104, CAN
  • Ability to comply with leading open standards specifications e.g., MESA and SunSpec
  • Authentication via certificates. Multiple levels of access and control for different user profiles
  • Controller offers seamless integration with a SCADA system or any 3rd party controller

APPLICATION STACKING

Through the Web Interface (HMI), applications can operate concurrently (stacks) with priorities (e.g. perform application 2 only if application 1 is not active). Applications can also be configured to use a certain percentage of the asset (application 1 has access to 60% of the BESS rated power, application 2 has access to 40% of BESS rated power). Furthermore, applications can be scheduled to operate certain days a week on certain hours of the day, or 24/7.

ROBUST DATA HISTORIAN

Fractal EMS includes a detailed data historian using web-based data retrieval for interactive visualization, analytics and custom report creation. All data is encrypted (including customer provided data) and is hosted with separate permission levels to maintain privacy and security of data. Time series data available for all interconnected components and systems to include: battery racks and management systems, unit controllers, meters, sensors, fire panel, thermal management, switchgear, transformers and generators. Fractal EMS captures and publishes data to the cloud in real time with unlimited data storage. This provides users the necessary data during warranty claims, technical dispute resolution, and feeds the predictive failure algorithms.

Fractal EMS allows operators to stack and deploy multiple applications with an intelligent scheduler back by multi-user permissions. Fractal EMS provides a Calendar that allows you to schedule application stacks and to schedule when your system will start/stop. Stacks are customizable, you can prioritize applications and configure individual parameters. Calendar events can be repeated, color coded and copied. Timeframes can be as short as one minute and as long as a year. In addition, the Calendar can accept schedules from 3rd parties (e.g., Fractal Model).
