Impact of short-term and long-term energy storage units on power system operation economy: A parametric linear programming method

چکیده
Abstract This paper evaluates the economic impact of short-term and long-term energy storage capacity on power system operation cost. First, unit commitment (UC) model with comprising a year-round hourly simulation is established to minimize optimal By introducing convex hull original feasible region decision variables, integer variables in UC are relaxed as continuous transforming problem linear programming (LP). Then, by regarding capacities parameters, LP cast multiparametric (mp-LP), where value function (OVF) explicitly expressed piecewise parameters. An approximation method used calculate analytical critical regions. The expression OVF contains rich sensitivity information. Finally, case studies validate our proposed provide visualization results. information exploited. As potential application, evaluation results could be applied sizing.

Financial intermediation in Iran's banking system is negatively affected at least in two ways. First, there are many similarities between financial intermediation and usurious activities in the common interpretation of interest-free banking law. This encourages the banks to participate in various commercial activities. Second, the price setting policies of the central bank makes investment more...

Background: Sickness absence is a major socio-economic problem imposing a huge amount of cost to societies.This issue has been widely concerned over the last few years. Absence from work entails complex conditions and multifactorial etiology. According to previous studies, there are various occupational and personal factors contributing to the incidence of sickness absence. Long-term sickness ...
متن کاملEffects of Neonatal C-Fiber Depletion on Interaction between Neocortical Short-Term and Long-Term Plasticity
Introduction: The primary somatosensory cortex has an important role in nociceptive sensory-discriminative processing. Altered peripheral inputs produced by deafferentation or by long-term changes in levels of afferent stimulation can result in plasticity of cortex. Capsaicin-induced depletion of C-fiber afferents results in plasticity of the somatosensory system. Plasticity includes short-term...
