5 Parts in electric Power Grid

Out of Control at DS???

Why can “IoT” be a potential solution to advanced DSM？ ◆  IoT = Internet of Things ◆  DSM = Electrical Demand Side Management ◆  IoT Based DSM = Smart electrical power app terminal cells + “Cloud” center + Big data analysis & coordinate center ◆  IoT based DSM could potentially achieve energy, space, facility, running intelligently management through information network platform and “Big Data” analysis, planning and administration.

How “IoT” Based DSM work？ If computers could take over all the DS loads simultaneously

◆ Power Demand Peaks shift ◆ Selective load shedding and control ◆ Optimizing energy consumption ◆ Multi-energy sources coordination ◆ Load monitoring, metering and protection ◆ Remote control to each specific load

What is the reason to R& D Smart Switch All switches connected between Supply side and Demand Side All switches on-off states need to be reported to IoT DSM All loads need to be measured and controllable by center of IOT Power + Security + Fire Control System should be in one with IoT

Key Solution to IoT DSM Solution of DSM Smart Grid IoT DSM Case Study Marketing

Marketing of IoT DSM 1. Energy-Internet is a very hot topic due to multiple forms of energy present 2. All energy forms need to coordinate with demand side, meanwhile keeping the power grid stable 3. Energy policy of every country focuses on green and energy saving 4. Internet has greatly changed human life style and still the fastest thing developing on this planet 5. The coverage of the internet matches that of the power grid 6. The speed of internet is faster than the power grid taking GPS technology in consideration 7. Only connection ties all the users together
