Internet of Things

"In the 'Internet of Things' the physical world becomes integrable with computer networks. Embedded computers or visual markers on everyday objects allow things and information about them to be accessible in the digital world." Dominique Guinard, ETH

The Smart Grid will be a large and complex system where the challenges of safety and security will be enormous. New network tools will need to be developed to manage the hetrogeneous nature of the physical makeup and no single application or protocol is likely to dominate this vast market of many physical, bahavioural and regulatory layers.

 

MicroGrids

MicroGrids comprise low voltage distribution systems with distributed energy resources, storage devices and controllable loads, operated interconnected with the main power grid or autonomously, in a controlled coordinated way. A critical security factor of MicroGirds is the control function, in place to manage the transition from upstream Grid connection to grid islanding due to disturbances or disconnection from the upstream grids. Storage systems are a key element in this security role but in addition, an efficient load shedding strategy is required to handle the problems resulting from limited storage capacity and from a generation deficient island. The plogg can be configured to operate as either a micro source controller or a load controller within the smallest of environments.

Distributed Generation Controls

Distributed generation (DG) of electricity is providing an increasing part of the worldwide electricity supply where efficiencies in distribution costs and micro generation can be realised. At the same time, there is a big potential to be gained from demand response resources. When the number of these Distributed Energy Resources (DER) increases, then the clustered control of the DER by common information and communication technology can add significant value. Due to the resolution and distributed nature of DER, the design of such a system needs to meet exacting requirements, e.g. regarding scalability and openness.

Around the world, building management systems are being developed to combine optimal energy management with consumer behaviour and ambient environmental conditions. Such control systems, operating through Home Gateways or Energy Smart Meters, will combine metering, monitoring and control functions with sensor and market price signals. Aggregation of household data will enable matching of demand with supply on a local basis, especially with intermittent renewable sources. Further, this will assist with imbalance conditions for suppliers and generators on the scale of the national grid.

The introduction of ZigBee Pro, with interoperability foremost in the design specification, will allow the plogg ZigBee to meet many of the requirements of smart agents – connection to other devices and upstream communication to local processing controls and price signals.
