Abstract The maximum power point operation of the photovoltaics (PV) restricts them to participate in frequency regulation connected system. Therefore, it is a common practice deload PV systems for generating an active reserve. However, deloading causes underrating these systems, hence additional panels are installed overcome reserved power. Since regulations can be achieved by using batteries,...

In the recent years, the solar energy becomes one of the most important alternative sources of electric energy, so it is important to improve the efficiency and reliability of the photovoltaic (PV) systems. Maximum Power Point Tracking (MPPT) plays an important role in photovoltaic power systems because it maximize the power output from a PV system for a given set of conditions, and therefore m...

This paper presents an improved control strategy for parallel inverters so as to better manage power sharing among the distributed generation units in a microgrid. The proposed control strategy combines both power and voltage control schemes implemented on the voltage source inverters which are used as power electronics interface systems for conversion of power generated by fuel cell and photov...

The most relevant basis for designing photovoltaic systems is their annual energy production, which is also the best metric for monitoring their long-term performance. An accurate array performance model based on established testing procedures is required to confidently predict energy available from the array. This model, coupled with the performance characteristics of other baiance-of-system c...

Hydrogen production via electrochemical water splitting is a promising approach for storing solar energy. For this technology to be economically competitive, it is critical to develop water splitting systems with high solar-to-hydrogen (STH) efficiencies. Here we report a photovoltaic-electrolysis system with the highest STH efficiency for any water splitting technology to date, to the best of ...

Recent work has proposed that hybridization of residential-scale cogeneration with roof-mounted solar photovoltaic (PV) arrays can increase the PV penetration level in ideal situations by a factor of five. In regions where there is a significant cooling load PV-cogen hybrid systems could be coupled to an absorption chiller to utilize waste heat from the cogen unit. In order to investigate reali...

Solar energy offers a pollution free and sustainable means of harvesting energy directly from the sun. Considerable effort has been directed toward maximizing the efficiency of end-to-end solar systems, including the design of photovoltaic cells [15, 26], engineering new photovoltaic architectures and materials [24], and solar tracking systems [4]. Solar tracking is especially important for max...
