‟ INGENIEUR ... the most impactful disruptive technology for Malaysia’s future electricity infrastructure is the anticipated substantial proliferation of renewable and distributed photovoltaic generation (greatly characterised by its high variability and uncertainty) into the energy mix portfolio of the generating systems. that will need to be reliable, maintenance-free, and interoperable. Some of the best-positioned companies may be suppliers of big data and analytical software that can help to extract meaning from the enormous amount of data flows that the Internet of Things will produce for the power systems. With sensors, networks and computer systems controlling these critical power systems, the consequences of cyber-attacks could be staggering. It will take a great deal of thought and planning, as well as collaboration with private sector vendors to create proper safeguards and keep them up to date as these technological advances continue. In terms of data security and personal privacy/autonomy, both business enterprises and Government policy makers will have to come together to craft the necessary regulations to protect the consumers and society at large. Only when these issues are addressed in parallel with adoption of these technologies can widespread adoption of IoT be successful. In terms of public policy, the Government will need to establish clear understandings of the privacy risks that accompany the Internet of Things. The ability to put sensors virtually anywhere – to observe the traffic on a residential street or to monitor a home’s electricity use – will undoubtedly raise serious concerns about how all that information will be used. CONCLUSION This article discusses at length the issues and challenges of the four identified disruptive 6 56 VOL VOL 75 55 JULY-SEPTEMBER JUNE 2013 2018 technologies that can significantly impact electricity grid infrastructure development planning and system operation for utility of the future. From the author’s viewpoint, the most impactful disruptive technology for Malaysia’s future electricity infrastructure is the anticipated substantial proliferation of renewable and distributed photovoltaic generation (greatly characterised by its high variability and uncertainty) into the energy mix portfolio of the generating systems. This in turn will greatly affect national electricity/energy security in terms of demand-generation balance, both for real-time system operation and short- term/medium-term operational planning resource dispatch. If it lacks rigorous power system security assessment strategic studies, there is increased probability of partial or full system collapse of the infrastructure, as System Inertia is expected to decrease in tandem with increase in the levels of solar photovoltaic/distributed renewable energy generation. System Inertia is very fundamental in the order of importance from real-time operation for rate-of-change-of-frequency (RoCoF) and frequency response when there is imbalance between generation and demand. Thus, the challenging issue of managing System Inertia and RoCoF is of utmost importance in order to secure Malaysia’s future electricity power system grid against increased probability of system collapse. Our national electricity utility company (TNB), being one of the world-class utility companies, will need to reimagine its future business enterprise strategies in light of the issues and challenges as discussed and highlighted here. And, it should be used as the guiding framework for reimagining TNB as utility of the future.
