This paper presents a probabilistic interval optimization (PIO) model for evaluating the problem of optimal power flow considering wind power integrated (OPFWP). In PIO model, the wind power is deemed as a probability interval variable to assess its profit and risk simultaneously. To be precise, the profit is manifested by the net decrease of generation cost between the same power system with and...
Architectural vulnerabilities in basic analog circuits that can be exploited to embed analog hardware Trojans are identified. Challenges of detecting the presence of analog hardware Trojans are discussed. An example is presented of a simple widely used reference generator that incorporates an embedded analog hardware Trojan that requires no extra circuit components, no area overhead, and that leaves...
A temperature to digital converter (TDC) that does not require either a reference generator or an ADC and that exhibits low supply sensitivity, small die area, and low power consumption is introduced. A prototype circuit designed to support power management applications over the [60 °C, 90 °C] temperature range was implemented in an IBM 0.13μm CMOS process with a 1.2V power supply for use as either...
Challenges of using standard circuit simulators to determine the presence or absence of undesired operating points are discussed. Examples are given of circuits and simulation strategies that show the presence of undesired operating points when they exist but other examples are given that show the same strategies can fail to show the presence of undesired operating points under modestly different...
We report the first GaN-based pulse width modulation (PWM) circuit for integrated GaN gate driver. This circuit is composed of a sawtooth generator and a comparator, both of which exhibit stable operation at temperatures up to 250 °C and operate properly at 1 MHz. The PWM circuit is able to generate PWM signals whose duty cycle is effectively modulated over a wide range by a reference voltage. This...
A parity space approach to fault detection by an optimal measurement selection is proposed for networked control systems (NCS). A distributed process, decomposed into p sub-processes with different sampling times, is modeled as a linear time-invariant discrete-time system by means of the lifting technique. In order to reduce the network load and data transmission cost, an optimal scheme, which manages...
To maintain smooth market transition, certain amount of annual energy contracts are allocated to energy suppliers in some Chinese electricity markets. From the viewpoint of cooperative game, an analysis on the contract allocation algorithm is presented. Unit net income is adopted to evaluate single buyer and generatorspsila utility, an analysis that under what condition single buyer and generators...
