1 ITU G.hn The low cost technology for real time Metering and SCADA communication G.hn = Any Wire Coaxial cables Electrical wires Telephone lines

2 Founded in ~40 members A single next gen PHY/MAC technology that runs over coax, phone lines, power lines G.hn is a family of standards PHY Layer and Network Architecture (PHY) G.9960 Data Link Layer (DLL) G.9961 Management (G.9962) MIMO for wireline (G.9963) PSD Management (G.9964) Coexistence standard G.9972 TR-069 Support (G.9980) More to follow What is ITU-T G.hn?

3 BPL/G.hn Communications What is new? BPL has progressed very quickly since it emerged in the mid-1990s Silicon speeds have moved from 384 kbps to 1,000,000 kbps in about a decade. Proprietary standards have been replaced in 2011 by the new industry standard of G.hn. In 2011 was introduced new plug and play, self healing SMI architecture New concept of solution supporting mass real time energy management, HAN connectivity, ripple control & other additional features Solution successfully implemented Supported by several meter vendors in 4 continents. EU EV project and backhauling of data all use BPL. BPL/PLC Technology Evolution 3

4 AMI business case a real time load control Energy savings by the automatic load control in households Utilities can benefit from better management/control of energy in households. This can be achieved only when an automatic load control system is implemented in the homes. The solution has to work in real time The results from the analysis conducted shows the willingness of users to manage their consumption *Source: CEZ 4

6 Power Balance [kw] Comparison of substation balance without and with 5 minute load management of hot water heating Power Balance with ripple Control of boilers Power balance without load management of boilers Time Measured balance on DTS Simulation of boilers performance according to switching times of ripple control and typical parameters of consumption TUV *Results by CVUT/CEZ 6

7 Substation business case - Real time integration of local renewable sources Energy and cost saving by eliminating the loss of locally produced renewable energy and avoid unbalance on the grid Utilities must keep the energy transmission at a constant level (50Hz) at all times according to the UTC By implementation of small local renewable resources of energy overproduction can occur, which is not controlled via SCADA (small resources under 33KW, sun collectors on the houses have capacity 4,8 KW) Without localized control overproduction goes to the MV grid and losses occur Voltages must be maintained between +10 % of 230 vac Over production of power from renewable resources can cause severe under/over-voltages on the grid, or frequency shift thus unbalancing the network Over-voltages can damage electric devices and appliances in the home such as computers and freezers LV transformer must become a delimiter of the smart Grid allowing for the creation of small MicroGrids cells consisting of several transformer stations 7

8 Real time components of distributed intelligence for load management The automatic load control performed by the meter energy limiter Technology: The Smart meter with integrated real time communication executing universal ripple control The semi-automatic management and prediction of energy consumption on the distribution substation level; data collection and processing to enable to allocate locally produced renewable energy in real time. Technology: Smart Concentrator Unit BPL/G.hn smart meter with Mbus Wireless communication SCU Integrated communication Technology: G.hn/BPL 8
