Integrating a photovoltaic storage system in one device: A critical review

Due to the variable nature of the photovoltaic generation, energy storage is imperative, and the combination of both in one device is appealing for more efficient and easy‐to‐use devices. Among the myriads of proposed approaches, there are multiple challenges to overcome to make these solutions realistic alternatives to current systems. This...

Concept Design of Hybrid Crane Vessel

Heerema Marine Contractors operates large crane vessels, which are exploited for installation works in the offshore oil and gas industry. The benchmark power system of these crane vessels is diesel electric meaning that the main engines are driving alternators for generating electric power. But due to spiky power demand and strict redundancy...

Energy Storage and Power Management for Typical 4Q-Load

Diesel generators in small electricity grids are mostly not used in a very efficient way. The reason for this is twofold. First of all, the efficiency of a diesel generator is dependent on the ratio determined by the average power divided by the peak power of the generator. The smaller this ratio is, the lower the efficiency. Furthermore, some...
