BenefitsUtility and Consumer• Keeping the Load and Voltage on a feeder or a grid section in line with network constraints

(feeder peak load lopping, zone substation peak load lopping, voltage control, reactive power

control, home inverter compensation, etc …)

• Economical Provision of Inertia and Operating Reserve, and Step-Load Capacity in a connected

or isolated grid section with mixed or hybrid generation

• Solar PV or wind generator intermittency smoothing, bridging, and transient ramping

• Smooth segregation and re-integration of a grid section on a feeder from/to island operation

• Black-start isolated grid in case of outage and trip

- Grid connections or distribution feeders

- Controllable loads (demand management/DRED)

- Home Energy Management Systems

assets are monitored and controlled to work collaboratively via the

PowerTec: “Parallel Distributed Electrical Assets Control System”

(PaDECS)”


Components are overlaid to the asset’s field controllers or protection devices, one controller each per asset.

PaDECS + BESS Stabiliser Control Targets


Sufficient provision of

• Microgrid Operating Generation Capacity The Microgrid Operating Capacity is to be larger than or equal to the actual load plus the set step load reserve minus any set power provided by a main network connection.

and, for certain configurations:• Microgrid “Operating Consumption Capacity”• Microgrid positive step-load reserve• Microgrid negative step-load reserve

Provided by the combination of all controlled and monitored asset in the

grid.

Thus, power supply reliability will never be compromised.

Freestyle Micro-engine (FME) operating system,

IoT Management Switch (FMS) local operator interface / GUI

“Fog” Server

The HVC-501-RRN Gateway & Controller is a novel, freely programmable system

with very versatile in-built communication features

- 2x RS485

- 2x Ethernet with TCP/IP protocols

- Zigbee, 3G

Communication options are implemented using daughter-boards

piggy-backed onto the mother board USB bus.

PaDECS« Fog Computing »


A cloud service with a specific server and network provides

- Application down-loads and Upgrades

- 1 sec cycle-time in whole distributed system updates

Programmability

The HVC5XX applications are freely programmable (in “LUA” scripting language);

Challenge: Single-thread Embedded programming and debugging is not easy

Modbus interfaces are defined via JSON descriptor files

Comparing IoT Control Systems –Vs. Central Control and Embedded Systems with Cloud Control

IoT control system vs. central controller or Cloud Controller:

- For large numbers of assets in a grid (hundreds)

- Parallel power functionality is more realistic than central functionality

- Automatically deploys the optimal Aggregated control strategy

- IoT Addressing: Integrate into the communication network, manage, deploy parameters, deploy software

updates vie EID addressing of Gateways & Field Devices

- Cheap Hardware (Gateways)

- Fast, real time (Fog Computing): 1s / updates for 100 homes

- Hard to program
