Abstract: In steady-state voltage stability analysis, as load increases toward a maximum, conventional Newton-Raphson power flow Jacobian matrix becomes increasingly ill-conditioned so power flow fails to converge before reaching maximum loading. A method to directly eliminate this singularity reformulates the power flow problem by introducing an AQ bus with specified bus angle and reactive power consumption of a load bus. For steady-state voltage stability analysis, the angle separation between the swing bus and AQ bus can be varied to control power transfer to the load, rather than specifying the load power itself. For an AQ bus, the power flow formulation is only made up of a reactive power equation, thus reducing the size of the Jacobian matrix by one. This reduced Jacobian matrix is nonsingular at the critical voltage point, eliminating a major difficulty in voltage stability analysis for power system operations.

Abstract: Various innovations for a transactive control framework with heterogeneous devices such as refrigerators, air conditioners, water heaters, and clothes dryers, or components of such systems/units, are presented. For example, an aggregator for the transactive control framework receives bids from device controllers for heterogeneous devices. Different bids can reflect different behaviors of heterogeneous devices under one transactive control framework, which allows the heterogeneous devices to participate in the same ancillary service market for power. The aggregator determines a cleared price value, then broadcasts the cleared price value and a regulation signal to the device controllers. The device controllers can use a stochastic decision-making process to regulate power utilization by the respective heterogeneous devices, such that the aggregate behavior of the controlled devices tracks the regulation signal.
