“…Even the establishment of power sources is not possible practically for some armed posts where they will consume only power (i.e., only load buses). Under this situation a locally established smart grid by interconnecting possible isolated microgrids can solve many problems including power quality, reliability, security, smart operation and uninterrupted supply [3][4][5][6][7][8][9][10][11][12][13][14][15][16]. The location of a smart grid can be selected based on the location where maximum Microgrids are possible for connection through a smart grid.…”

Many isolated locations, including hilly areas, remote sites, and military camps, lack feasible access to the main power grid. In these conditions, locally established Microgrids can provide the necessary power supply. However, to meet the demands of these isolated areas, numerous individual Microgrids are required. Although some of these Microgrids might be integratable, geographical constraints may preclude full integration. Under these circumstances, the establishment of a smart grid – integrating multiple Microgrids with a battery management system – can potentially solve many power supply issues. A smart grid control system paired with a centralized battery management system is proposed in this paper. The system considers the use of multiple renewable energy sources at various locations for stable and reliable power generation. The proposed method incorporates a long short-term memory (LSTM)-based artificial neural network (ANN) to ensure a stable, high-quality power supply at different load buses. Additionally, this work introduces an artificial intelligence-based operating system designed to maintain energy management under various conditions. To enhance voltage quality, a 7-level aligned multilevel inverter is incorporated into the system. As compared with PI and Fuzzy controllers, the proposed method with LSTM-ANN controller is improved the power quality under sudden changes in the system which are also presented in results. The effectiveness of the proposed energy management system (EMS) is verified by using a hardware-in the-loop approach with OPAL-RT modules, yielding realistic results.

Asynchronous or induction machines are among the leading devices in the electrical industry. They are well suited for motor and production applications with power ratings from a few kilowatts to megawatts. In addition, their use in renewable energy systems, especially in wind conversion systems, is increasing daily due to their advantages, such as low cost, brushless, and robust structure. In this work, the operation of a three-phase asynchronous motor with a winding rotor as an alternator, the variation of the voltage produced depending on the excitation current by keeping the number of revolutions constant, and the interpretation of the voltage produced according to the number of revolutions by keeping the excitation current constant have been investigated. The variation of the terminal voltage in ohmic, inductive, and capacitive loads has been experimentally investigated by observing the source voltage providing the rotational speed and excitation current constant.

“…In the industrial sector, induction motors are used in numerous applications due to their characteristics like reduced maintenance, easy operation and robustness. During the operation of induction motor, some harmonic contents are produced which in turn affects the overall system function and this issue is rectified by power factor correction (PFC) method [1]- [4]. Considering the severe PFC requirements for power electronic devices, significant progress has been achieved in the creation of effective PFC converters.…”

In general, the induction motor (IM) is extremely nonlinear in nature and frequency dependent. In most cases, the power generated by the IM has a low power factor (PF), which exhibits detrimental effect on the extent to which the whole transmission and distribution system functions. Since there exists more current harmonics as an outcome of minimized PF, the efficiency of the power system suffers due to transmission line heating and voltage distortion characteristics. Therefore, this paper proposes a power factor correction (PFC) method to overcome the aforementioned issues. Here, by the utilization of AC-DC bridgeless SEPIC-Cuk converter, the power quality is improved by reducing reactive power consumption and enabling better control of voltage and current outputs. To maintain the stable DC link voltage with reduced ripples, the adaptive proportional-integral (PI) controller is used in this work. The three-phase voltage source inverter (VSI) transitioning function is controlled by cascaded fuzzy logic (CFL) controller, which is also utilized for regulating the speed of the three-phase IM. Implementing the proposed control strategy improves power quality significantly by reducing total harmonic distortion (THD). The proposed system is simulated in the MATLAB platform and the attained outcomes, it is clear that the proposed system is highly effective.
