“…The logic behind this is to simulate the consumption of various types of energy within the building and calculate carbon emissions based on the carbon emission coefficients of these energy sources. Internationally recognized energy simulation software includes EnergyPlus, OpenStudio, DesignBuilder, DesT, IES-VE, and TRNSYS, among others [4]. EnergyPlus is a widely used international energy simulation engine, and it includes a program for whole-life cycle calculations.…”

As the economy continues to advance, and the populace's demand for material well-being grows, urban areas are witnessing an increasing need for electricity supply. Substations, playing a pivotal role in the power industry, are proliferating in terms of both quantity and construction scale. Reinforced concrete substation buildings are a common infrastructure that provides a suitable physical environment for the operation of power equipment. A thorough examination and analysis conducted through on-site investigations have unveiled deficiencies in the low-carbon design and operation of substation buildings, resulting in energy wastage and extra carbon emissions. Consequently, this study endeavors to introduce a method for calculating carbon emissions during the operational phase of reinforced concrete structure substations. It also presents corresponding strategies for low-carbon design and operation. These strategies encompass low-carbon design principles for the building envelope structure, the utilization of renewable energy, low-carbon design considerations for artificial lighting, and the implementation of intelligent environmental control systems. The strategies proposed in this research provide valuable ideas for making the power and construction industries more environmentally friendly and energy-efficient.

This manuscript proposes a hybrid approach for multi-functional grid connected photovoltaic (PV) interleaved inverter using power quality improvement. The proposed approach is a combination of Spherical Evolution Search Algorithm (LSE) and Wild Horse Optimizer (WHO), therefore it is called LSE-WHO approach. The main objective of the proposed approach reduces DC voltage fluctuation and improves power quality. The interleaved inverter is utilized at the grid side, which consists of four legs and every leg contains a power electronic switch and a diode. Due to the configuration of interleaved inverter shoot-through effect is overcome. The system performance is enhanced by the utilization of interleaved inverter. The proposed approach operation is classified into 2 parts such as power harvesting and the harmonics reduction. The LSE approach is utilized to extract the maximum power of PV and the WHO approach is utilized to reduce the harmonics distortion and eliminated the DC link voltage fluctuation through double band hysteresis current controller (DBHCC). DBHCC provides lesser switching frequency, hence, the switching losses is low. By then, the LSE-WHO approach is implemented in the MATLAB site, its performance is compared to the existing approaches. From the simulation, it is conclude that the LSE-WHO approach provides the THD as 2.12% and increase the power quality.

“…Compared with other traditional topologies, T-type topology delivers an extraordinary improvement regarding the lower count of switches used and lower layout complexity. Further, almost 40-50% reduction in power switch count is achieved without diodes or capacitors [173]. This configuration has an H-bridge and an auxiliary bidirectional switch for controlling the connection of the supply from the DC sources to generate the staircase output voltage.…”

In recent years, multilevel inverters (MLIs) have emerged to be the most empowered power transformation technology for numerous operations such as renewable energy resources (RERs), flexible AC transmission systems (FACTS), electric motor drives, etc. MLI has gained popularity in medium- to high-power operations because of numerous merits such as minimum harmonic contents, less dissipation of power from power electronic switches, and less electromagnetic interference (EMI) at the receiving end. The MLI possesses many essential advantages in comparison to a conventional two-level inverter, such as voltage profile enhancement, increased efficiency of the overall system, the capability of high-quality output generation with the reduced switching frequency, decreased total harmonic distortions (THD) without reducing the power of the inverter and use of very low ratings of the device. Although classical MLIs find their use in various vital key areas, newer MLI configurations have an expanding concern to the limited count of power electronic devices, gate drivers, and isolated DC sources. In this review article, an attempt has been made to focus on various aspects of MLIs such as different configurations, modulation techniques, the concept of new reduced switch count MLI topologies, applications regarding interface with renewable energy, motor drives, and FACTS controller. Further, deep insights for future prospective towards hassle-free addition of MLI technology towards more enhanced application for various fields of the power system have also been discussed. This article is believed to be extremely helpful for academics, researchers, and industrialists working in the direction of MLI technology.
