Cloud Computing for Advanced Power System Monitoring Eugene Litvinov, Chief Technologist, ISO New England Eugene Litvinov, Chief Technologist, ISO New England The rapid proliferation of new technologies is transforming how electricity is produced, delivered, and consumed. While offering many benefits, these changes are also increasing the complexity of power systems and requiring innovative approaches to keeping the lights on. As the operator of a six-state high-voltage power grid, ISO New England (ISO-NE) is pioneering the use of cloud computing in the power industry for these purposes. One such initiative is exploring cloud computing’s ability to reliably, securely, and cost-effectively manage large volumes of high-resolution data generated by the region’s new phasor measurement units (PMUs). These devices measure key elements of power system dynamics about 100 times faster than was previously possible, giving power grid operators such as ISO-NE an unprecedented view of real-time grid performance—as well as the challenge of processing an unprecedented amount of data.
