Alencon Solar Energy Systems


Alencon provides high-efficiency inverter technology targeted at large-scale photovoltaic systems. “Our energy conversion architecture needed a system that would scale. We chose RTI Connext DDS.”

-- James Ethridge, Principal Software Engineer

ABB – Next Gen Substation Automation NGSA

• Beachhead into ABB & Smart Grid

• ABB are leading IEC 61850 standard

• Technical Eval. outperformed ABB’s performance requirements

• Connext ProDDS Pro for Linux, Windows, VxWorks 7.x


IIC Microgrid Testbed • Goals

• Efficiently use solar, wind, & EVs

• Create an open marketplace

• Prove viability DataBus

• Leads

• RTI: DDS middleware and system integration

• NI: Engineering software and hardware

• Cisco: Grid communications

• Phases

1. Proof of Concept at National Instruments

2. Realistic simulation at Southern Cal Edison

3. Live test at CPS Energy San Antonio Grid of the Future


Goal: Generate more than load

Today’s Grid Wastes Solar Power

Power Plants Central Station Sub Stations Distributed Load

15-min state estimation “Spinning reserves”

Balance grid with frequency control

Add solar: add

uncertainty

Need more reserves!

Solution: Field Message Bus

Power Plants Central Station Sub Stations Distributed Load

State estimates more stable Much lower “spinning reserves”

Local loops connect generation, load, & battery storage Goal: Generate

more than load


Local Loops & Storage Reduce Spinning Reserves
