Demand-Side Management by Regulating Charging and Discharging of the EV, ESS, and Utilizing Renewable Energy

Abstract: The evolution in microgrid technologies as well as the integration of electric vehicles (EVs), energy storage systems (ESSs), and renewable energy sources will all play a significant role in balancing the planned generation of electricity and its real-time use We propose a real-time decentralized demand-side management (RDCDSM) to adjust the real-time residential load to follow a preplanned day-ahead energy generation by the microgrid, based on predicted customers’ aggregate load A deviation from the predicted demand at the time of consumption is assumed to result in additional cost or penalty inflicted on the deviated customers To develop our system, we formulate a game with mixed strategy which in the first phase (ie, prediction phase) allows each customer to process the day ahead raw predicted demand to reduce the anticipated electricity cost by generating a flattened curve for its forecasted future demand Then, in the second stage (ie, allocation phase), customers play another game with mixed strategy to mitigate the deviation between the instantaneous real-time consumption and the day-ahead predicted one To achieve this, customers exploit renewable energy and ESSs and decide optimal strategies for their charging/discharging, taking into account their operational constraints RDCDSM will help the microgrid operator to better deal with uncertainties in the system through better planning its day-ahead electricity generation and purchase, thus increasing the quality of power delivery to the customer We evaluate the performance of our method against a centralized allocation and an existing decentralized EV charge control noncooperative game method both of which rely on a day ahead demand prediction without any refinement We run simulations with various microgrid configurations, by varying the load and generated power, and compare the outcomes

Morphine-dopamine interaction: Ventral tegmental morphine increases nucleus accumbens dopamine release

Abstract: Microdialysis and high-performance liquid chromatography with electrochemical detection were used to determine extracellular levels of dopamine following ventral tegmental morphine injections into chloral hydrate-anesthetized rats. Morphine (13.2 nanomoles in 0.5 microliter of Ringer's solution) caused 50-150% increases in nucleus accumbens dopamine and metabolites; latency for the effect was on the order of 15 min with peak effects occurring in 30-50 min. Contralateral dopamine levels were influenced only minimally. These data suggest opiate receptors in or near the ventral tegmental area as sites of the opioid action that is responsible for opioid activation of the mesolimbic dopamine system.

Development of advanced FDD and FTC techniques with application to an unmanned quadrotor helicopter testbed

Abstract: As the first part, this paper presents an overview on the existing works on fault detection and diagnosis (FDD) and fault-tolerant control (FTC) for unmanned rotorcraft systems. Considered faults include actuator and sensor faults for single and multi-rotor systems. As the second part, several FDD and FTC techniques developed recently at the Networked Autonomous Vehicles Lab of Concordia University are detailed along with experimental application to a unique and newly developed quadrotor helicopter testbed.

What Do We Know About Private Family Firms? A Meta-Analytical Review

Abstract: The universe of family firms is heterogeneous, and findings gleaned from publicly listed firms may not apply to the ubiquitous, but less frequently studied, privately held family firm (PFF). As PFFs are insulated from capital market pressures, owner-managers have greater latitude in setting strategic goals, which may result in different strategic choices and performance outcomes. By employing meta-analytical techniques on 48 studies conducted in nine countries, we synthesize prior PFF research. We show that PFFs prefer more conservative strategies, but contrary to received wisdom, this risk aversion does not hurt their performance. We conclude with an agenda for future research.
