been overlooked. This is an important problem faced by service providers, especially in the current multi-electricity market, where the price of electricity may exhibit time and location diversities. Further, for these service providers, guaranteeing quality of service (i.e. service level objectives-SLO) such as service delay guarantees to the end users is(More)

—This paper studies the fundamental dimensionality of synchrophasor data, and proposes an online application for early event detection using the reduced dimensionality. First, the dimen-sionality of the phasor measurement unit (PMU) data under both normal and abnormal conditions is analyzed. This suggests an extremely low underlying dimensionality despite(More)
—This paper proposes modeling the rapidly evolving energy systems as cyber-based physical systems. It introduces a novel cyber-based dynamical model whose mathematical description depends on the cyber technologies supporting the physical system. This paper discusses how such a model can be used to ensure full observability through a cooperative information(More)

— In this paper a model of a future combined cyber-physical energy system is introduced. We view such systems as the intertwined physical-cyber network interconnections of many non-uniform components, such as diverse energy sources and different classes of energy users, equipped with their own local cyber. This modeling approach is qualitatively different(More)
In this paper, a model predictive control (MPC)-based coordinated scheduling framework for variable wind generation and battery energy storage systems (BESSs) is presented. On the basis of the short-term forecast of available wind generation and price information, a joint look-ahead optimization is performed by the wind farm and storage system to determine(More)
—This paper proposes a novel approach to utilizing large online synchrophasor data for early event detection in power systems. Based on principal component analysis (PCA), a linear basis of the massive online phasor measurement unit (PMU) data can be extracted to reduce the dimensionality. Using the linear basis with much reduced dimensionality, an early(More)
