unified Dynamic Response Converged Power Solution


Solution/product description

The Unified Dynamic Response Converged Power Solution provides a new power and control architecture for MSO transport networks. All network elements and critical infrastructure (power systems, HVAC, lighting, etc.) are connected through a common control element for energy management and a unified power solution serves all energy requirements with greater simplicity and efficiency. Reporting on energy requirements from APSIS managed network elements is used to better utilize and plan infrastructure power and cooling usage. The automation system manages seamless transitions between alternate energy sources based on demand response and demand history, to include grid power, renewables, energy storage, and local generator operation. These transitions are possible due to the 380Vdc based converged power system that can supply AC and DC loads without the need for large UPS, AC switchgear, automatic transfer switches, etc. The system monitors, controls, and enhances efficiencies of three main components of the HVAC system; hydronic pumps, heat absorption equipment, and heat rejection equipment to align facility cooling versus critical load. The Converged Solution can include high efficiency dynamic cooling systems optimized for specific locations.

How does your project address / improve the focus area (Monitoring and Measurement, Demand Response, Supply and Control)?

The first step in providing optimized demand response is to implement monitoring and measurement for proper reaction to dynamic conditions. This is done by gathering data from network elements and critical infrastructure components and comparing to historical data which is fed into an algorithm. The converged power system manages seamless transfer as necessary between grid, generator, energy storage, and renewables to supply power to all of these optimized loads. Cooling system energy use is also optimized, allowing CRAC Units, AHU, Chillers, Pumps, Towers, etc. to be managed dynamically according to load requirements and ambient conditions.

What was your inspiration for your project?

Delta/Eltek has been deeply involved in energy reclamation and efficiency improvements for some time but has realized the only way to true energy utilization optimization is through a broad, encompassing solution that addresses the facility as a single system. Individual subsystems need to be coordinated and dynamically respond to feedback in harmony like a living organism without manual intervention or processing.

What is the single most exciting thing about your project?

We believe this solution provides the benefits of proven hyperscale custom facility designs in a way that can be applied to legacy multi service operators. This solution provides a new architecture for powering the network, using industry proven components in a more efficient and more reliable manner. It allows for centralized monitoring, control, and reporting of all power needs with automated dynamic response for maximum PUE not just in a single facility but across the entire network.
