“…At the same time, the energy market is being disrupted by a shift toward renewable energy sources, both on a grid scale and through distributed generation.. Following graphs shows the individual load profiles [30][31][32][33]: (Residential; Small commercial; Medium commercial; & Large industrial load profile). From the observation of the graphs it can be concluded that (i) during evening hour residential load profile shows maximum demand & small commercial load profile indicates that load is maximum during noon hours, (ii) medium commercial & large industrial load profile indicates flat load demand from morning to evening hours.…”

Wind energy conversion systems are becoming very popular these days, and wind energy generating stations use wound rotor induction machines a lot. This is because wound rotor induction machines can be used with wind turbines with variable speeds. This makes it possible to get as much energy from the wind as possible. Also, using a Doubly Fed Induction Generator (DFIG) configuration with back-to-back pulse width modulated voltage source converters (VSC) is one of the best topologies that are currently available for wind power systems with induction generators. This topology works for both systems that are connected to the grid and systems that work on their own. In this work, a quick look at all of the control schemes for both the stator side converter and the rotor side converter is given in a stator flux-oriented reference frame, and the results are compared based on cost, efficiency, power consumption, and harmonics.

“…Kuczy ński et al proposed that in temperate European countries, building residential buildings with heavy envelopes and partitions would significantly reduce overheating in the next few decades [33]. Additionally, the closing of external blinds can also be considered to alleviate this phenomenon [34].…”

Global warming is resulting in higher summer indoor temperatures in the severe cold region and cold region of China, and this is affecting thermal comfort. Local building design codes consider these regions as cool in summer, and do not consider the phenomenon of overheating or propose countermeasures. This paper studied the possibility of overheating in residential buildings in these areas. It suggested alleviating this phenomenon using external horizontal shading, and discussed how to integrate thermal comfort into the building design and save energy consumption. The IESVE software was used to simulate 18-storey residential buildings with natural ventilation in Yichun, Harbin, Shenyang, Dalian, and Beijing, and to calculate the change in indoor operative temperature. Horizontal shading was designed for case study building to attempt to alleviate the overheating phenomenon in summer. The results showed that the case study building in the five cities experienced different degrees of overheating. External horizontal shading was successful in reducing indoor overheating, especially in the severe cold B and C zones and the cold A and B zones. The relevant building codes should be modified to take this into account. Reasonable design of horizontal shading can effectively reduce energy consumption, particularly when compared with air-conditioned buildings.

“…Results showed that natural ventilation is a very beneficial approach to extract heat, accounting for a percentage of a circa 80% reduction [22]. T. Kuczynski et al (2020) also established that, when night ventilation is introduced in a quick and effective manner within a building with a high thermal mass, temperatures during the night hours no longer reached the absolute maximum temperatures, thus improving the indoor ambient environment [23]. M. Darmanis et al ( 2020) also highlighted the use of night ventilation as a beneficial cooling strategy in regions where the diurnal temperatures are very high (30-35 • C).…”

Prioritising Passive Measures over Air Conditioning to Achieve Thermal Comfort in Mediterranean Baroque Churches

et al. 2022

Malta, as a member of the European Union (EU), has pledged to become carbon neutral by the year 2050. Concurrently, the need for thermal comfort for people within places of worship has expanded tremendously in recent years. As a result, prioritizing passive methods over mechanical air-conditioning systems in such buildings is an essential step toward protecting the macroclimate while achieving a sustainable and comfortable indoor environment. Using DesignBuilder-EnergyPlus software, this paper examines the effectiveness of selective passive measures in two free-running church buildings. Results show that certain passive measures alleviate severe high and low indoor temperatures, resulting in a more comfortable environment. Environmental control, on the other hand, present difficult conservation challenges. Historic church buildings were initially built to make use of passive design features for internal comfort, and this study shows that they outperform expectations and, in general, outperform more contemporary church structures.
