An Experimental and Comparative Analysis of the Battery Charge Controllers in Off-Grid PV Systems
The study of the battery charge process as the only power storage agent in off-grid systems is of significant importance. The battery charge process has different modes, and the battery in these modes is dependent on the amount of charge. In order to charge the battery in off-grid systems, two charge controllers including Pulse Width Modulation (PWM) and Maximum Power Point Tracker (MPPT) are c...
متن کاملA Sufficiency Paradox: An Insufficient Statistic Preserving the Fisher Information
An example of a regular statistical experiment is constructed where an insufficient statistic preserves the Fisher information contained in the data. The data are a pair (∆, X) where ∆ is a binary random variable and, given∆,X has a density f(x−θ|∆) depending on a location parameter θ. The phenomenon is based on the fact that f(x|∆) smoothly vanishes at one point; it can be eliminated by adding...
متن کاملOptimal battery storage operation for PV systems with tariff incentives
Many efforts are recently being dedicated to developing models that seek to provide insights into the techno-economic benefits of battery storage coupled to photovoltaic (PV) generation system. However, not all models consider the operation of the PV – battery storage system with a feed-in tariff (FiT) incentive, different electricity rates and battery storage unit cost. An electricity customer...
متن کاملTechno-economic evaluation of self-consumption with PV/battery systems under different regulation schemes
The recent disclosure of new and innovative home battery systems has been seen by many as a catalyser for a solar energy revolution, and has created high expectations in the sector. Many observers have predicted an uptake of combined PV/Battery units, which, could ultimately disconnect from the grid and lead to autonomous homes or mini-grids. However, most of the comments originating from socia...
متن کاملComputing Efficiency, Sufficiency, and Self-sufficiency: A Model for Sustainability?
Computing is an activity that is based on natural resources like any other human activity. Technological progress has made it possible to perform more and more computations with less material and energy input. This paper looks at this development through the lens of the three concepts of efficiency, sufficiency, and self-sufficiency, asking the question of whether it could lead to a state of se...
