easYi

benefits

• reduce complexity on your supervisory control / energy manager control by delegating control functions to a sub-level controller, which makes it easier to build up your microgrid controller
  (please read this article for explanations in a similar scenario)
• control AC networks as simple as DC networks
• helps customers to focus on core project specific tasks: control the energy flow and SCADA and visualization
• increase system stability and reliability with Hot Swap redundant communication between controls
• Standardized control boxes that work with all kind of engines, generators, inverters, breakers (*1)
• Back-Up mode: peer-to-peer controls with basic Microgrid operating modes if master control and safe backup power mode if other units fail
• Capability for simulation of the control system before project realization; work through realistic use-cases before commissioning including the interconnection to your Microgrid / Supervisory / Energy Management System
• can simplify the wiring and reduce the need for distributed PLC modules
• seamless integration into easYgen3000XT and LS-x networks
• simplifies scalability of the microgrid

product description

• Various application modes off-grid, on-grid, as well as Import / Export control in dual mode (*2)
• Running each DC power sources in AC island operation and/or parallel to the grid operation (*2)
• Controlling constant power/reactive power flow
• Controlling frequency and voltage in island operation (*2)
• It is a basic battery charging guide by determining the correct moment for charging and discharging the energy storage
• Manage a careful battery charging (battery balancing)
• Indicate operation modes, setpoints and alarms of the inverter and DC power source and react accordingly (*3)
• Interact with combustion engines controls (easYgen3000XT), breaker controls (LS-5 or LS-6) and other controls in a system
• Support power management systems and SCADA systems
  – Guide the Inverter and DC sources via interface (prepared for interfacing with all kinds of Modbus TCP based inverter systems, Modbus Master Mapper to modify protocols according to inverter and BMS protocols)
• Operate the DC breaker
• Operate the AC breakers
• Indicate operation modes, setpoints, alarms of the inverter / DC power source and react accordingly
• Decide the best moment for charging the energy storage based on operator parameter
• Allow other Inverter manufacturer and DC sources to operate by an open function structure
• Black start capability
• Balance safe operation and maximizing renewable sources:
• Supports optimized dynamic spinning reserve calculation to make sure lowest numbers of diesel gensets are running to save fuel (in island mode and if necessary at all)
• Curtailing of solar power to avoid operating diesel gensets in reverse power or below low load operation

Strategic Differentiation: What does the easYi not do?

Woodward’s easYi works as a lower “level 2” controller. Meaning our customers build, design and commission “level 3” supervisory controls / Microgrid controls / energy managers. Please read this article to align the interpretation of control levels.

• system visualization
• Optimization of energy management and decision logic
  (eg. optimize economic or environmental performance)

   

  • consumed power and available power
  • economic aspects (e.g. optimal use of renewable energy) and thus the selection of the most suitable application modes
  • Load shedding / peak load management and management based on economic or
  • Generation of schedules or plans and readjusting them
  • rules or forecasting (power generation forecast based on weather forecast, load forecast, energy trading and power prices, asset management and connection to external processes…)
• Optimizing the combination of heat and electricity generation
• Woodward is a sub-supplier and not the one contact for the entire project
• Financing support
• ‘Return on Invest’ calculations and graphs for end-customers
• Statistics and Data: storing and analyzing electrical data of production sources and consumers (daily/weekly/monthly/annually)
• Smartphone app connection / online visualization of plant data
• Interface to building automation system

Notes:
*1: Woodward can provide the relevant communication mapping and functionalities to support different inverter controls and battery management systems based on previous projects.
*2: requires an inverter with grid-forming mode capability
*3: depending on the available alarm flags of the Inverter- and BMS controller
