SYSTEM DESCRIPTION
System Overview
Go Electric Inc’s. LYNC DR® and LYNC Secure® systems are designed for two design purposes
but with multiple capabilities. The systems are designed for utility grid applications and/or grid
independent microgrid applications.
Utility Grid Dependent Connection:
The Go Electric, Inc., LYNC DR® or LYNC Secure® uninterruptable energy system
incorporates patented AutoLYNC® technology to provide a method for synchronizing to and
from a utility grid.
The key innovation in this technology is the ability to synchronize and connect to an AC
utility grid while simultaneously maintaining power to a critical load (if applicable). The
fully equipped microgrid design allows the LYNC DR® and LYNC Secure® systems to
switch between various modes of operation while controlling current in a bi -directional
manner and maintaining IEEE519 conditions on power delivered to the utility grid and/or
critical load (if applicable).
If the utility grid experiences inconsistency such as phase loss or complete failure, the system
will automatically sense the grid failure a nd will switch its control state accordingly. The
system will either disconnect from the utility grid or go into a stand-alone operation mode if
alternate power sources are available. Otherwise, the system will shut down in accordance
with UL 1741SA and IEEE 1547 performance standards. The utility grid connected device
has two purposes:
• Provide a stabilizing influence on the grid by augmenting power.
• Provide ultra-fast backup power to a specific electric customer.
A single system can serve either or bot h purposes. In combination, they can meet a variety
of business needs.
Utility Grid Independent Connection:
For Go Electric, Inc’s utility-independent systems, the LYNC DR® and LYNC SECURE®
uninterruptable energy systems incorporate the same patented AutoLYNC® technology to
provide a method of connecting and utilizing any renewable energy resource to provide
power to a critical load. The key innovation in this technology is the ability to u tilize
renewable resource, i.e., photovoltaic inverter systems, as the primary source of power to the
load. If necessary, the LYNC DR® and LYNC SECURE® system can also synchronize to a
generator to provide power to a critical load as required. This system would provide energy
resiliency for any application that cannot have a utility grid application but does have a
renewable energy resource available.
7
System Architecture
Go Electric Inc. utilizes a multi-layer microgrid architecture that delivers best-in-class microgrid
performance & customer value streams.
Figure 1 Multi-Layer Architecture
Physical Layer:
AutoLYNC® seamlessly integrates any AC or DC DER, including, switchgear, generators, solar
PV, DC batteries and the grid for maximum microgrid flexibility. This enables multiple value
streams for the customer.
Microprocessor Layer:
A microprocessor is combined with each DER in the physical layer, which allows Go Electric
Inc. to control in real time all the DERs with simple commands, maintain microgrid stability , and
prevent any load or generation runaway. This is a critical capability for overall microgrid contro l.
8
Real Time Control Layer:
This layer is high speed fiber that connects LYNC DR® or LYNC Secure® to each
microprocessor which give this layer four key features.
• Fast (milliseconds)
• Deterministic
• Master-less
• Scalable
This layer utilizes multiple communication protocols, such as Modbus TCP or 485, CANbus,
DNP3, SCADA, etc.
Microgrid Orchestration Layer:
This is your classic microgrid controller, however, in the Go Electric Inc. architecture, the
microgrid controller does not route every command and communication between the DERs.
Instead, it is the conductor that tells the other DERs what mode to operate in, from which
point each DER can talk to each other directly. This allows for low latency communication
throughout the microgrid. This layer seamlessly integrates with any building management
system and can program specific economic set points to deliver maximum value streams to
the customer.
Macro Grid Orchestration Layer:
This layer provides an OpenADR 2.0b utility portal to aggregate, monitor and command the
microgrid, as well as a customer interface with real time data. Customers can see their
facilities load, energy savings, and demand response income.
9
System Interface
High Voltage Interface
The LYNC DR® or LYNC Secure® systems require a 3-phase high voltage 480VAC
connection from the utility grid. The critical load connection supplies voltage to an outside
source if the utility grid is lost. The system also requires a high voltage DC connection from
the external battery or renewable energy source. Use the Installation Manual for the
installation of the high voltage DC and AC connections. The high voltage electrical
connections for the utility grid and critical loads are labeled on the system. The utility
enclosures are provided for protection against high voltage electrical contact.
Controls Interface
LYNC DR® or LYNC Secure systems are Open ADR 2.0b enabled, allowing any utility or
end-use customer to directly communicate with and control the energy storage system . It has
an aggregation portal built right into the control panel, and a customer -friendly, web-based
interface for 24/7 monitoring. The system can also be outfitted with customized LCD
monitors as well as many different communication protocols: Modbus TCP or 485, CANbus,
DNP3, SCADA, etc. For more information on the Controls interface, see the HMI Manual
(if applicable).
HIVETM
The HIVETM is a self-contained switchgear solution that reduces the time to design and
install a microgrid. Simply put, the HIVETM is the center of the microgrid in that it is the
junction for all electrical connections (minus the battery) for the LYNC Secure® system,
generator(s), photovoltaic system and loads. The HIVETM is two different cabinets: The
Switchgear and the Control Center Cabinet. Inside the Switchgear is a series of different
breakers, switches, and power electronics to feed power to the loads from either the LYNC ®
Secure system and/or the generator(s). The Control interface monitors and controls the
HIVETM through custom software that allows microgrid configuration to be adjusted and
controlled.

SYSTEM OPERATION
Grid Parallel Operation
The patented Go Electric solution continuously monitors system parameters, makes intelligent
decisions, and autonomously responds within micro-seconds to control power production, power
distribution and loads, and provide VAR support for improved efficienc y. The ability to respond
at the very fast micro-second level is a key advantage of the Go Electric solution over other
energy storage systems. In normal operation, both the internal Grid Breaker and Inverter Breaker
are closed and the LYNC DR® or LYNC Secure® system is on. In this mode system is
programmed to keep the attached energy storage system at an optimum level in the event of a
utility loss. The LYNC DR® or LYNC Secure® system also performs the following services in
this mode:
• DER Optimization:
AutoLYNC continuously monitors the utility power, load profile, DERs, and can make
intelligent dispatch decisions based on economic and operational parameters. For
example, LYNC DR® can time shift PV production based on the local utility tariff and
net metering laws.
• Instant Commutation of DER’s, (such as PV):
LYNC DR® or LYNC Secure® is an auto-grid forming energy storage system that
commutates renewables. The system has shown that it can carry a solar PV inverter
through a utility disconnection event without losing PV production, a game -changer for
energy storage systems. This capability has been verified by NREL’s third party testing at
its facility in Golden, CO.
• Peak Shaving:
LYNC DR® or LYNC Secure® lowers peaks and reduces demand charges which saves
money on utility bills.
• Power Factor Correction:
LYNC DR® or LYNC Secure® is capable of injecting and withdrawing reactive power
(VAR), which will correct undesirable power factor levels. This will increase the overall
efficiency of the power on the local circuit and any connected DERs, as well as avoid any
power factor penalties, if applicable.
• Voltage and Frequency Droop Control:
Sophisticated techniques within our software allow the LYNC DR® or LYNC Secure® to
maintain the correct voltage and frequency regardless of power demands. This allows our
system to operate in parallel to other energy sources. Microgrids incorporating LYNC
technology experience more balanced load sharing while charging or dispatching power.
• Volt - Watt:
Sophisticated techniques within our software allow the LYNC DR® or LYNC Secure® to
actively limit the active power output (watts) to be equal to or less than the active power
15
output as a function of the voltage. This will maintain the correct voltage and frequency
regardless of power demands.
• Voltage - Var:
Sophisticated techniques within our software allow the LYNC DR® or LYNC Secure® to
adjust VARs to keep grid voltage from oscillating; acts like a shock absorber . Intended
result is automatic stabilization of grid voltage if the grid voltage is nominal, purely
active power. If the grid voltage is high, add ‘inductive’ reactive power. If the grid
voltage is low, add ‘capacitive’ reactive power.
• Frequency Watt:
Sophisticated techniques within our software allow the LYNC DR® or LYNC Secure® to
support grid frequency by changing inverter wattage output. If grid frequency is nominal,
inverter is at max output. If grid frequency is high, inverter curtails power. If grid
frequency is low, inverter increases power if available.
• Power Synchronization:
LYNC DR® and LYNC Secure® autonomously matches voltage, frequency, phase angle
and wave form allowing a seamless transition from Grid Disconnected Mode to Grid
Parallel operation.
• Grid Services:
LYNC DR® can be Open ADR 2.0b certified allowing for communication with utilities
and ISOs. This enables the system to earn revenue from demand response, capacity,
voltage, and frequency regulation, regulating reserves, etc.
Interruption of Utility Power
LYNC DR® and LYNC Secure® are the only patented UL certified AC-based, parallel UPS’ on
the market that is capable of automatically disconnecting sub-cycle from the utility grid, creating
a seamless power transfer from grid connected to grid isolated, and vice -versa. While this
transition to a stand-alone operation in less than 50ms or 3 waveform cycles will generally not
flicker lights, turn off computers, or heavy machinery, there will be a slight disturbance in the
wave form, as a grid disturbance is the integral element to triggeri ng the isolation event. Once a
grid disturbance is detected, the LYNC DR® or LYNC Secure® system will instantly change its
control status to grid forming, correct the disturbance in the power output, and then open a
breaker, providing a seamless transfer to grid-isolated mode. One of the features of the
LYNC DR® and LYNC Secure® systems are that existing renewable inverters will not see a
power interruption and will continue to produce power in this grid disconnected configuration.
Operation without Utility Power
The LYNC DR® or LYNC Secure® systems can continue to support customer critical loads for a
length of time determined by your site design. The system can autonomously manage generators,
PV sources, wind energy and battery reserves. Once the system senses the utility supply has
16
returned, it will automatically, after a programmed delay, synchronize the critical load to the
utility and reconnect without interruption.
Return of Utility Power
Once the LYNC DR® or LYNC Secure® senses the utility supply has returned, it monitors phase
and voltage data via high-speed communications. The system will then gradually adjust its
voltage phase and frequency to match the utility grid to transition back to grid parallel operation.
When the system sees the microgrid and utility grid are in phase, it automatically reconnects; all
without interrupting the critical and non-critical loads.
17
