How to Protect a Smart Grid from Threats in the Future

How to Protect a Smart Grid from Threats in the Future

Cyber terrorism is the nightmare scenario for the energy industry. Fear, uncertainty and doubt (FUD) are the weapons of choice.  In the ‘good old days’ we worried about hurricanes, tornadoes, earthquakes, and wildfires taking down transmission lines.  Because transmission was always more difficult to site, permit and build due to NIMBY and the eternally long process of environmental and regulatory review.  We compensated for that uncertainty by building more power generation, closer to load centres.

Energy Machine Learning

In addition, because the power grid was not designed from the top down but rather represented the slow process of interconnecting utilities first for back up, then for power sales of excess generation, the power grid has always been fragmented.  Even today there is no national grid but rather four large regional power grids that connect most of North America.

Reliability has also been the holy grail of the power system and the natural gas pipeline system.  Utilities and energy suppliers were expected to keep the lights on and the gas flowing.

Along the way the process of approving interstate natural gas pipelines changed shifting responsibility for permitting, siting and approval to the Federal Energy Regulatory Commission (FERC).  Maybe it was because gas pipelines were buried underground but there was much less public opposition to their construction.  And when there was FERC listened politely to the complaints and worries and then approved the projects trying to reasonably mitigate the most serious problems.

Electric transmission remained a state by state regulated function and that made all the difference—mostly for the worse.  The NIMBY issues got more vocal, the tortured process for transmission construction was interminable and the costs were outrageous. States liked it that way because it helped them retain their regulatory jurisdiction and kept utilities on a short leash.

Renewable energy, the desire for greenhouse gas emissions reduction and the political correctness of smart grid combined to change the dynamics.  Wind resources in West Texas or Iowa, solar energy intensity in the Southwest or geothermal in Nevada and California were stranded without the transmission to get them to load centres.

Smart grid was designed to improve power grid efficiency and security by expanding the scope and scale of the grid to make power electronics, grid automation, demand response and other benefits possible.  But unifying the grid also makes it more vulnerable to resource inadequacy and terrorist attacks.

Energy Learning Machines

So today while we don’t hear the term energy fear, uncertainty and doubt (FUD) that is what NERC, FERC and energy industry trade groups, regulators and utilities executives worry about most.

That is why we should pay more attention to the risk potential of things like Stuxnet and now Flame that appear to be doing their dastardly deeds on Iranian nuclear facilities.  Those same threats could be just as easily worming their way through any of North America’s power grids.  Protecting against that requires both thinking big and thinking small.   Thinking big is exactly the kind of important work that NERC is doing to establish standards and implement security protocols to secure the grid with preventive measures and procedural security consistently executed by every utility and regional transmission organization.

Analysing Energy Production

Predictive Energy Analytics

Future proofing the grid also requires thinking small about microgrids and a modular framework for dynamically compartmentalizing the grid to prevent problems from cascading out of control and developing the workarounds essential to restore stability quickly.  Visual network analysis, artificial market simulation, scenario analytics, and dynamic grid automation is the way of the future.  It will require new tools and old concepts of self-sufficiency, reliability, resource adequacy and a mix of resources to allow each modular sector of the power grid to fend for itself, heal itself, secure itself, and feed itself in emergencies.

A power grid future that rejects fossil fuels and undermines base load generation that prevents new nuclear, new hydro from being built consigns itself to the most volatile fuels, the most volatile transmission congestion and the longest wait to get the light back on.  Solar energy especially rooftop solar in load centres offers the only real potential for microgrid modularity because it small scale allows the resource to be sited quickly and everywhere.

Energy FUD today is about a lot more than just cyber terrorism.  It also is made possible by policies that undermine fuel diversity, resource mix between reliable, low cost base load, low cost peaking resources, and the natural gas fired load following resources in between to assure system reliability.  Energy FUD is defeated by balance, diversity, modularity and flexibility.  That should be both our strategic as well as operational security priority.

    Liquid Fueled Thorium Reactors (LFTR) can be made very small and if chosen would reduce the size of the grid and with it the size of the problem this article discusses.

    That is just one of the very many benefits that they deliver. In passing, it should be noted that they can burn the nuclear waste generated by the outdated fleet of Light Water reactors currently deployed. (There is an entertaining TED talk by Kirk Sorensen on the matter.)
