“…Active and reactive power reference based load sharing, conventional droop control and MPPT based droop control are proposed to extract power from DGs and send to load/grid, but here PV and storage are considered independently [18][19][20]. A multi-input transformer coupled bidirectional DC-DC converter is proposed in [21][22][23][24], here DC voltage regulation is taken care by Inverter in grid-connected mode. But in Islanded mode of operation, battery and DC-DC converter have to look out and PV is forced to operate in non-MPPT mode to maintain voltage regulation.…”

DC microgrids are gaining popularity as most of the residential loads like Televisions, BLDC fans, LED bulbs, Mobile phones and other electronic gadgets are DC in nature, but to connect Distributed DC generator (DG) to DC bus, DC-link voltage is to be maintained at the reference value. In the proposed work, a transformer coupled dual input converter control strategy is modified by replacing existing Perturb & Observe Maximum power point tracking controller with − / based droop controller, which amalgamates DC bus voltage regulation and Maximum power point tracking (MPPT) of PV source and battery state of charge (SOC) in single controller, and eluding controller switching between voltage regulation and MPPT modes. The proposed system will also work as Decentralized droop control for load sharing, and applicable for both islanded and grid-connected operations. Load Power sharing between DG sources is achieved according to its droop coefficient values in DC side of the inverter, thus suitable for DC Microgrid, and results are verified by simulating the above system in MATLAB/Simulink.

“…Being the two fastest growing sources of power generation from renewable energy sources, several studies have shown the benefits (the complimentary nature of solar irradiance and wind speed [195][196][197][198]) of hybrid generation from a mix of renewable energy sources such as wind and PV systems [199]. Other distributed energy resources (DERs), such as battery energy storage [200] and most recently tidal [201], have been proposed as part of a composite hybrid system to address the challenges of power generation from PV systems alone.…”

Integration of high volume (high penetration) of photovoltaic (PV) generation with power grids consequently leads to some technical challenges that are mainly due to the intermittent nature of solar energy, the volume of data involved in the smart grid architecture, and the impact power electronic-based smart inverters. These challenges include reverse power flow, voltage fluctuations, power quality issues, dynamic stability, big data challenges and others. This paper investigates the existing challenges with the current level of PV penetration and looks into the challenges with high PV penetration in future scenarios such as smart cities, transactive energy, proliferation of plug-in hybrid electric vehicles (PHEVs), possible eclipse events, big data issues and environmental impacts. Within the context of these future scenarios, this paper reviewed the existing solutions and provides insights to new and future solutions that could be explored to ultimately address these issues and improve the smart grid's security, reliability and resiliency.

A B S T R A C TThe conventional approach for the integration of multiple renewable sources and energy storage elements involves using dedicated single-input converters for each source and requires more number of converter stages leading to considerable reduction in relia and efficiency of the system. In order to address this issue, a power control strategy of a PV-wind-battery based grid connected single phase power generating system with an efficient multi-input dc-dc converter is proposed. This syste load, maintain the power flow between different sources, inject surplus power into the grid and charge the battery as and when required. A bidirectional buck for harnessing power from PV source with battery charging/disc transformer coupled boost half-bridge converter is used for harnessing power from wind source. A single-phase full-bridge inverter is used for feeding ac loads and interaction with grid. The proposed converter configuration has reduced number of power conversion stages with less component count, and reduced losses compared to existing grid systems. This improves the efficiency and reliability of the system. Simulation studies using MATLAB/Simulink are carried out to verify the viability of the proposed system under various modes of operation depending on availability of sources and change in load.
