<p>A modern and expanding civilization now takes for granted that future environments will be clean, efficient, and carbon neutral. Energy-efficient electrical loads, such as v ehicle charging now often u sed in schools, companies, and gated communities. Recent articles have focused more on Swarm smart grid technology as a way to transmit power from rooftop solar installations. A major issue with the system is the necessity for inverters and other conversio n equipment. The mechanism consumes part of the power generated by this process. It is possible to utilize the DC supply to power the v ehicle chargers in smart houses, although some tweaks may be necessary. The charging Vehicle is a common task that can sh are by different converter by swarm network. This study demonstrates the feasibility of using a swam nano grid t o interconnect buildings inside a campus or other large business or residential complex, as well as within a gated community. The electricity gr id is monitored by the swam nano grid system, which eliminates the need for costly equipment. The DC - DC converter was being controlled directly by the simple logic controller. M ATLAB Simulink simulates the controlled converter under load and shows the performance of a bidirectional DC-DC converter using waveforms.</p>

“…This component converts the PV-produced variable DC voltage into a fixed voltage that is proportionate to the load requirements. The MPPT controller simultaneously works to achieve MPP conversion from PV and provide a pulse width modulation (PWM) signal to drive the DC-DC converter's switching mechanism [22], [23], [25], [27], [28], [32], [38], [39], [42], [43], [52], [77], [81], [93], [94], [98], [108], [112], [121]- [146]. These two processes happen simultaneously.…”

“…Additionally, when buck-boost converters operate in continuous conduction mode (CCM), the input current is smooth and continuous with very little ripple. The voltage and current stress placed on components by two-switch buck-boost converters is significantly lower than that of single-switch buck-boost converters [22], [42], [53], [81], [87], [97], [102], [103], [115], [117], [119], [125], [133], [138], [142], [146], [164], [168], [222], [225], [263], [264], [266], [288], [289], [308]- [320]. Ahmed et al [315] present a twoswitch non-inverting buck-boost converter with the possibility for extra current storage.…”

Solar photovoltaic (PV) power generation has become increasingly important as a renewable source of energy due to the many benefits it offers. These benefits include the ease with which it can be allocated; the absence of noise; the longer life; the absence of pollution; the shorter amount of time required for installation; the high mobility and portability of its parts; and the capability of its output power to meet peak load requirements. DC-DC converters are typically incorporated into solar energy harvesting systems because they allow for the more efficient exploitation of solar cells. One of the difficulties is in the selection of a suitable converter since this has an effect on the operation of the PV system. This study discusses the modernisation of several different DC-DC converter topologies for solar energy harvesting systems. Some of these topologies are boost, buck-boost, single-ended primary-inductance converter (SEPIC), Cuk, and flyback. The topologies have been compared so that detailed information on the complexity of the hardware, the cost of implementation, the efficiency of the energy transfer elements, the tracking efficiency, and the efficiency of the converters can be provided. This paper will be useful as a handy reference in choosing the best converter topology for solar energy harvesting applications.

<span lang="EN-US">Model predictive control (MPC) has recently been ranked as one of the best modern technics of control for high voltage direct current (HVDC) based on voltage source converter (VSC) transmission systems, since it is a simple controller, understandable and can be implemented easily, also has a dynamic and fast response. The classic double closed loop PI controller has many disadvantages such as the difficulty in determining the Kp, Ki, and Kd parameters as well as the couplings; It is also less robust against systems with slow dynamics and/or having a complex structure. This paper exposes a model predictive control for a two-level converter. Direct power control on rectifier-side based on model prediction and on the inverter-side AC current control strategy is proposed. The controller utilizes the identified model to anticipate the comportment of the output voltage of every switching state at each sampling frequency. At the next sampling interval, the optimum switching state is applied using the cost function as a reference point. The MPC method was verified by the tools of the MATLAB/Simulink software. The simulation results validate the feasibility and effectiveness of the presented control strategy.</span>
