TL;DR: Time-domain simulations of each of these structures are discussed to confirm the need for the DDC to make a shift from conventional single-input-single-output (SISO) based two-port DDC configuration to the multi- input-multi- output (MIMO) based multiport designs.
Abstract: DC-DC power conversion, ranging from volt-fraction to ten of kVs, and mWs-MWs, is found in various applications, the latter making a human’s life comfortable. DC motor drives [1], telecommunications [2], satellite [3], fuel cell electric vehicles [4], are among many other such applications. The literature reports a large number of topology, and design variants of a DC-DC converter (DDC) as in [5]– [17] and references within, to achieve an improvement in the efficiency [18] of the DC-DC power conversion. The advent of novel configurations enables the DDC to make a shift from conventional single-input-single-output (SISO) based two-port DDC configuration to the multi-input-multi-output (MIMO) based multiport designs. This article highlights the need of this structure shift by detailing the SISO, multi-input-single-output (MISO), single-input-multi-output (SIMO), and the MIMO DDC structures. Afterward, this brief discusses time-domain simulations of each of these structures to confirm the aforesaid structure shift.

TL;DR: This paper shows that implementing hierarchical control for the residential distributed generation paves way for the power-sharing across different community grids thereby upgrading the existing AC smart grid operation.
Abstract: The recent advancements in renewable energy technologies is empowering residential consumers to meet their energy requirements from locally installed renewable energy devices and energy storage devices. In this context, the adjacent microgrids can interact and share these resources using a stable strategy through which economic, environmental and operational advantage can be gained. In this paper a three-level hierarchical control is introduced into residential houses to effectively share the power between houses coming under the community microgrid in such a way that users will get power at an optimized price. The hierarchical control algorithm is developed for primary control (Local control center), secondary control (Microgrid control center) and tertiary control (Upstream control). This paper shows that implementing hierarchical control for the residential distributed generation paves way for the power-sharing across different community grids thereby upgrading the existing AC smart grid operation.

Abstract: One of the major challenge in the power generation is heavily depends of thermal power plant based on coal, at the same time for construction of coal based thermal plant there is restriction from environment aspects, so it is necessary to promote renewable energy like solar and wind energy generation. In case of installing the hybrid energy system, the main causes behind requirement of this installation is the intermittency of various energy resources and unbalanced quantity of sources of energies. The performances of solar PV and wind turbine connected hybrid generating systems are much better in conditions where the sunbeam and wind shifts their rate of availability based on the seasonal changes. A hybrid arrangement of combining the power harnessed from both the wind and the sun and stored in a battery can be a much more reliable and reliable and realistic power source. But, still the load can be powered through the energy stored in the batteries even when there is absence of solar or wind. Hybrid system is usually built for design of system with lowest possible cost and also with maximum reliability. The high cost of solar PV cell makes it less competent for larger capacity designs.
