“…It is possible for asynchronous networks to be interconnected with long-distance networks in a way that is particularly effective, both economically and from the perspective of transmission system performance. The basic HVDC system interconnection is illustrated in Figures 1(a By using HVDC to connect different PV technologies, transmission and distribution losses can be minimized when transmitting power over great distances [20]- [23]. In this case, DC-DC boost converter topology utilized to increase the panel low voltage to the high voltage DC level.…”

High voltage direct current (HVDC) transmission is flexible towards the power control (produced by solar or wind) and can be transported over thousands of kilo meters with minimal losses over the high voltage alternative current (HVAC). It allows solar power to be integrated into the current power grid on a large scale. The author view in this article aims at providing an overview of methods used to integrate HVDC and solar systems. MATLAB/Simulink is used to simulate the solar power integration with HVDC transmission link. This article emphaises solar energy and grid integration, which results in quality and controlled electricity to the grid. Further the simulation studies are compared with real time data between the stations Pugalur AC grid (high solar energy region) and Thrissur AC grid (low solar energy region). Obtained results from the simulation, voltage and currents and power quality stresses the superiority towards the solar integration. The comparison studies enumerate the need to go situation for HVDC technology during the penetration of solar voltaic penetration into the utility network.

“…In addition, the absence of electrical isolation makes it impossible to ensure the distributed power system's level of safety. For these reasons, the isolated MPCs are the most used in EVs and RES applications due to they have more advantages over than the non-isolated converters such as isolation between the input and output stages, offer a high output voltage for the DC bus link especially in grid tied PV inverters applications [44,45]. This kind of converter may be further subdivided into three subtypes based on the nature of the connection between the three ports: (i) non-isolated converters, (ii) partly-isolated converters, and (iii) isolated converters, as seen in Fig.…”

Appropriate design of Multi-Port Converter (MPC) topology helps to overcome the difficulties of combining numerous renewable energy sources (RES). In this article, a comprehensive analysis of these MPCs in terms of their topologies, operating principles, various dependability, and overall efficacy is offered. There are two main types of MPCs which are non-isolated and isolated MPCs being coupled in parallel and series configurations to function as multi-input converters. These MPCs can flow the load power in one or both directions for the RES or BESS (battery energy storage system) applications. The non-isolated MPCs are most used in the latest years but they have some limitations such as small voltage gain, and failure in isolation. The isolated MPC is more effective than the non-isolated ones in terms of isolation between the input power stage and output but has some drawbacks such as the high cost, and large size of the high-frequency transformer (HFT). In this review paper, a high-efficiency voltage-regulator/battery energy storage system (VR-BESS) was presented as a multi-port DC-DC converter for the standalone PV (photovoltaic) array. This converter has fewer switches, is cheaper, and is more dependable than its counterparts.
