This 10-page white paper argues that utilities must move to automated demand response in place of older "manual" load management programs, particularly in the energy-intensive industrial sector. Although written by a vendor, this is a well-researched piece that sheds light on the need to -- and the techniques for -- shedding "fundamental loads" such as refrigeration, pumps and material handling systems. The recommended solution is an extension of factory automation that connects many loads, decides which subsets will be used to respond and makes decisions based on preset rules.
Is it possible for you to help me to find the meaning of intelligent smart grid?
Thanks a lot for your attention
Best Regards

The Smart Grid is a bi-directional electric and communication network that improves the reliability, security, and efficiency of the electric system for small to large-scale generation, transmission, distribution, and storage.
IEEE Definition:
“an automated, widely distributed energy delivery network characterized by a two-way flow of electricity and information, capable of monitoring and responding to changes in everything from power plants to customer preferences to individual appliances.”
“a smart grid is the electricity delivery system (from point of generation to point of consumption) integrated with communications and information technology”

Smart Grid Secuirty Assumed
A common public assumption is that the grid is and will be secure. Currently this is far from the case, as there are few standards and protocols in place to enforce this notion. Without true, built-in security as a fundamental basis of the grid, further build-out of the grid is actually exposing us attacks and vulnerability, not lessening it. Basically, the underlying infrastructure needs to be rebuilt from a security and privacy standpoint to utilize secure processes, protocols, and governance, such as white hat protocols, 'air space' between critical components, non-IP based communications and the use of non-public OS, non-windows based hardware and software. Until this actually happens, most of the grid investment is at risk and the continued push by both vendors and the government only exacerbates the increasing national security risk that is the unsecured 'smart grid'. (Please note this is my personal opinion and not necessarily that of my employer.)

New petition for evidence quality in SmartGrid ops
Folks we have a formal petition up before the California PUC we want you to know about. It is a petition to amend CPUC rule making and data storage standards established 30 years ago to ‘address digital evidence standards’ set in the California Appellate Court in California v Khaled, also known now as “the Red-Light Camera Killer”.
Khaled set very specific standards for Court admissibility of Evidence in California Courts and this created a set of standards all unmanned or automatic devices would have to produce evidence to. The key concept of the ruling is the making that evidence trustworthy, and being able to say it was reliable information.
With the ease of how GPS and other RF based systems are hacked these days, and the issues with how easily digital content is fabricated by unscrupulous parties this becomes a real issue when compounded by the millions of simultaneouls users attached to the Grid.
As such quality evidence standards are critical to TOU billing programs and for administering DA and ESP services through AMI/AMR service models.
To make this all real – we need you to write the CPUC a note and tell them you think that reliable evidence, what P1007015 seeks to bring to the California Utility Code and its enforcement is a good thing.

Natural gas is getting so cheap that it may become cheaper and faster to slap up a gas-fired peaking plant than to implement a complicated demand response or renewable project - two of the biggest drivers of a smart grid. Yikes! Will natural gas alternatives make the smart grid too expensive by comparison? That's this week's Tuesday Topic in our discussion forum. Please join in.
