Evolution7 Applications – Compact Network Management

•  Hierarchies of GridAgents can be used to:

–  Manage and reconfigure compact networks

–  Dispatch DER –  Maintain PQ –  Dispatch DR –  Isolate buildings,

MicroGrids, or feeders. –  Facilitate energy market

transactions –  Intelligent Condition

Monitoring –  Integrate with Building EMS

systems and HVAC



Projects: MicroGrid 2011 - Integral EU project

–  Develop and validate

innovative control strategies and network architectures for active networks with large-scale penetration of renewable sources and distributed generation

–  Increase market exposure of small ‘prosumers (consumers with local generation)

–  Normal and Critical Operating Scenarios

Solar Microgrid Functions


Powering the 21st Century Economy

A Very Different Future?

•  As the number of loads and generators connected to the grid increases; –  the controllability and control model of the grid will change –  reliability will only be maintained through distributed intelligence and

control

•  Complexities at the edge – DR programs, DG programs, MicroGrids, grid divorce, AMI / HAN

•  This strongly suggests a more highly distributed energy system will play a major role in the modern grid.


Hybrid Integrated Systems (Microgrid) Trends

•  MicroGrids will con1nue to be an important niche for high-‐reliability and emerging markets (premium product or grid parity driven)

•  Integrated systems with capabili1es to locally reduce the renewable genera1on variability (VRG) in output will increase the viability of renewables

•  Predic1on that hybrid systems (Renewables and natural gas, Renewables and storage, Grid-‐Friendly Renewables) will become the next mass market product (Grid Variability + Economics + Risk Reduc1on + Co-‐loca1on with home solar and Electric Vehicles == Solar Microgrids
