Traditional electricity grids are pretty ‘dumb’, they continuously send out specific amounts of electricity until some engineers tweak that amount to meet the needs of the users. Smart grids, on the other hand are designed to monitor electrical supply and usage at any time, so they can adjust the creation and consumption of power, manage storage of surplus electricity, and so save energy, reduce waste and improve ...view middle of the document...
They then have to manage their supply and their demand to avoid penalties for over or under-usage, and they try to minimize load shedding, which is always possible but results in lost revenue and irate customers.
To implement economic dispatch, the eggheads at Auckland wrote an algorithm using the function block language of IEC 61499. This algorithm is set up in a number of intelligent “agents” each independently working towards the common objective - minimizing the total cost of operation of generators. The use of IEC 61499 enables system level design and testing of the entire system. The system level design simplifies distribution and deployment and allows for easy re-configurability and maintenance of multi-agent software. The developed industrial agents are platform independent and interoperable.
To test this algorithm they programmed five Advantech ADAM-6600 pico-controllers each with an “agent” as if each was connected to a different type of power generator. The cost of generation from each agent is then monitored, and depending on the consumer demand a decision is made on sourcing.
There are already more than a million ADAMs installed around the world, monitoring a huge range of devices; now, with the ADAM-6600, the information that they receive from these devices can be used to make decisions and take actions – take control. Advantech is leading the development of low-cost, distributed control systems with its ADAM-6600 range of Ethernet-based, ARM Cortex powered pico-controllers....
