Virtual Power Plants

In this study, an inexact two-stage stochastic linear programming (ITSLP) method is proposed for supporting sustainable management of electric power system under uncertainties. Methods of interval-parameter programming and two-stage stochastic programming were incorporated to tackle uncertainties expressed as interval values and probability distributions. The dispatchable loads are integrated into the framework of the virtual power plants, and the support vector regression technique is applied to the prediction of electricity demand. For demonstrating the effectiveness of the developed approach, ITSLP is applied to a case study of a typical planning problem of power system considering virtual power plants. The results indicate that reasonable solutions for virtual power plant management practice have been generated, which can provide strategies in mitigating pollutant emissions, reducing system costs, and improving the reliability of power supply. ITSLP is more reliable for the risk-aversive planners in handling high-variability conditions by considering peak-electricity demand and the associated recourse costs attributed to the stochastic event. The solutions will help decision makers generate alternatives in the event of the insufficient power supply and offer insight into the tradeoffs between economic and environmental objectives.

The Way

While we already know that clearly utopian or dystopian depictions of human-machine relationships in science fiction film can be effective rhetorical models that shape our ideas of HRI, this paper argues that sci-fi films, like Marjorie Prime (2017) and Be Right Back (2013), can also function as more neutral virtual laboratories that allow viewers to actively explore the pros and cons of those relationships in more detail. This paper specifically explores both Marjorie Prime and Be Right Back for the way they evoke questions or ideas about what it means to be human, what it means to interact with AI, and what a meaningful relationship between these two can bring. By following a neoformalist analysis, I will show how these cases continuously present us with devices that force us to reassess the role of robots in our lives. They do this by using deceptive, reflective, and confrontational strategies within characters, cinematography, narrative structure and setting.
