Occupancy-aware heating, ventilation, and air conditioning (HVAC) control offers the opportunity to reduce energy use without sacrificing thermal comfort. Residential HVAC systems often manually-adjusted or constant setpoint temperatures, which heat cool house regardless of whether it is needed. By incorporating occupancy-awareness into control, heating cooling can be used for only those time periods Yet, bringing this technology fruition dependent on accurately predicting occupancy....
Bayesian and nonlinear least-squares methods of calibration were evaluated compared for gray-box modeling a retail building. Gray-box model is one form system identification examined here with perturbations to the simple yet popular European Committee Standardization (CEN)-ISO thermal network model. The primary objective was understand whether computational expense probabilistic techniques required provide robustness signal noise, specifically regard lower dimensional problems (physical or...
This paper proposes a novel application of modular multi-level converter (MMC) for photovoltaic (PV) generation system to maximize the efficiency in partial shading conditions. A DC/DC boost is placed between each sub-module (SM) MMC and PV array extract maximum power. Furthermore, proposed topology enhanced with an independent active/reactive power control strategy demand response purposes. The effect circulating currents also minimized using proportional resonance (PR) controller....
Abstract Advanced district thermal energy systems, which circulate water at temperatures near ambient conditions, and facilitate the utilization of waste heat renewable sources, can lower carbon-intensity urban districts, advancing U.N. Sustainable Development Goals. Optimization network topology — selection best subset buildings to connect them, minimize life cycle cost increase adoption these system in appropriate applications. The potential “solution space” optimization problem grows...
