Title of Speech: Smart Energy and Smart City Big Data Analytic
Abstract: Smart Cities research and
development nowadays is becoming one of the prime interests pf the academic,
business, industry and government platforms. Smart cities provide its citizens
with smart services such as smart heath, smart transportation, smart homes,
smart buildings, smart factories, smart utilities and smart environment
services. Talking about all these fancy services brings about the concept of big
data. For example smart grid generates big data from sensors, consumers’
devices, meters, distribution transformers and substations, IEDs, SCADA,
distributed energy and historical data. This data can be characterized and
classified based on volume, velocity, variety, veracity and values (5Vs). The
data will be integrated, cleansed, filtered, sorted, stored, analyzed,
visualized and then monetized using data mining tools.
This talk will highlight the smart cites major pillars and services. A case study on big data sources and analytics in smart grid will be discussed.
In an effort to find out if the same big data techniques can be applied to monetize all the smart city big data, the speaker hopes to open the floor to get some constructive feedback from the audience.

Title of Speech: Islanding Protection of Network with Distributed Generator
Abstract: In this presentation, Professor
A.H.A. Bakar discusses the power system reliability in particular the protection
of the network. The reliability of the protection network depends among others
the reliability of the protection schemes. Failure of the protection scheme or
the mal-operation of the protective relays will have catastrophic effect on the
network. Widespread outage will occur, hence it will cause millions of dollars
lost. To restore the supply, it will take some time depending on the complexity
of the network. In order to avoid widespread outage most utilities adopt a
defence scheme whereby during abnormal conditions the network will split into
islands. For the island to survive there must be immediate load and generation
balance, as an example during the Northeast blackout the New England Island
With increasing concerned of the use of fossil fuels in conventional power plants, distributed generation (DG) such as solar PV, wind turbines, fuel cells, small scale hydro, tidal wave and micro turbines are gaining commercial and technical importance across the globe. They are preferred for their high energy efficiency (micro turbine, fuel cell), low environmental impact (PV, wind, hydro. A high degree of DG penetration as well as placement and capacity will have considerable impact on operation, control, and protection of the network. The area that is critically affected by large DG penetration is the protection coordination of the utility distribution system with bidirectional fault current flows. Further challenges are the impacts of steady state and dynamic behaviour of the DG on transmission system operator.
When the degree penetration was low, anti-islanding was imposed worldwide to prevent accidental islanding of DG. This feature is still being practised for personnel safety at the grid. Anti-islanding forces the DG to be disconnected immediately in the event of grid faults and loss of main. With the rapid growth of DG, DG penetration across the globe has significantly increased to a high level. This has resulted in reassessment of anti-islanding protection as it prevents utilization of DG for enhancement of power quality and reliability.
Various low cost and efficient digital islanding protection schemes are being developed, tested and validated through extensive research activities. Fast and efficient microprocessor-based islanding protection systems are suitable for operation of the active distribution networks both in stand-alone and grid connected mode. They can also ensure seamless operation of the inter-tie CBs for reconnection of the island zones without affecting original protection of the utility grid. The objective for islanding protection is to detect the power island condition to trip the inter-tie breaker between the power island and the utility. The power island will not affect the orderly restoration of the utility supply to the rest of the network. The tripping time for the island protection should be fast enough such that the two systems are successfully separated first before any out-of-synchronism reconnection attempt by automatic enclosure. Presently a maximum separation time of 0.5 seconds is recommended. The fault level of DG Power Island is much less than that of the grid and short circuit backup protection must be properly coordinated with this tripping time. The utility grid relays are too costly for DGs. For economic viability, there is a need for low cost completed DG protection. The use of a single unit microprocessor based relay with integrated protection functions is the best solution.
