The global utility landscape is undergoing a fundamental shift. Distributed renewable generation continues its growth becoming a larger portion of the energy equation, while customer consumption patterns adjust based on the increased adoption of electric vehicles, IoT devices, smart homes, and more. This ecosystem creates a new network model that cultivates a more dynamic and transactional relationship between the utility and its customers in optimizing both power delivery and energy management. Data is also increasing not only in volume, but in velocity and complexity and are presenting opportunities to deliver greater value, faster. To capture these benefits, utilities require new, flexible solutions and are turning to a hybrid approach – leveraging a centralized platform supported by distributed monitoring, intelligence and control. The Elpis Squared (Elpis) Flex ControllerTM is a flexible sensing and computing platform designed from the ground-up with utility operations and system planning in mind. Providing local measurement, data aggregation, and a framework to support dynamic coordination and control, Flex Controllers provide a unified gateway in monitoring and managing power in a distributed model. The Flex Controller is built within an open and scalable architecture that integrates with existing utility back-office systems and/or natively within the Elpis Re|GridTM ecosystem. Its versatile computing platform allows stakeholders from different organizations to configure customizable features and functionalities based on business and technical needs.

Achieving the New Approach The diagram below demonstrates basic functionality of the Flex Controller and its potential interaction with downstream components focused on grid, supply or demand side management. The Flex Controller establishes connection with these downstream devices and provides the visibility and control supporting a variety of applications with autonomous control and/or backhauling data to a centralized location for further system analysis and action. Enabled with the flexibility to manage various applications based on specific requirements, utilities can focus on taking action and delivering insights quickly and accurately based upon a particular situation in any given area – that’s redefining grid optimization.

Distributed Intelligence with Local MV & LV Sensing Dynamic grid optimization requires an agile infrastructure that supports both real-time power measurement and a network to exchange information between strategic nodes to make informed and autonomous decisions. The Flex Controller enables this infrastructure in one unified platform. The Flex Controller supports three configuration options:

1. Flex Controller-Base: This configuration provides the foundational data analysis platform and networking framework to collect and analyze local data, and communicate and control distributed assets.

2. Flex Controller-PQ: This configuration builds on top of the base platform and integrates a native Medium Voltage (MV) or Low-Voltage (LV) sensor to provide local measurement at the point of coupling.

Medium Voltage (MV) Specification: • Line voltage up to 15KV • Voltage sensing provides a 120V output, 0.5% accuracy • Current sensing provides a 5A output, 1% accuracy • Effective fault current detection up to 12kA • Measures up to 66th harmonic • Acts as a line post insulator; live line installation

Low Voltage (LV) Specification: • Single Phase 3-wire 240VAC • Polyphase 4-wire 120-277VAC • Polyphase 4-wire 120-480VAC • Transformer rating up to 167KVA • Compliant to ANSI C12.1 and C12.20

3. Flex Controller-XPQ: This configuration supports the ability to externally connect 3rd party PQ sensors to the Flex Controller. This allows utilities to take advantage of existing inventory of sensors and modernize its capabilities with distributed intelligence.
