TL;DR: In this paper, an improved average power control method is presented to regulate the power flow to the super capacitor, and a dynamic system model is designed using Matlab/Simulink.
Abstract: Electric propulsion is used in wide range of vessel types and applications. In marine vessels, the load of the power plant changes substantially over time, such as from the wave disturbances or the weather influence, which may cause large and also rapid changes in the load of prime movers. In this paper, to reduce the effects of the disturbances of the power plant and to improve the energy efficiency of the power transmission and power generation, a hybrid converter based on super capacitor is considered for fast-acting energy storage. An improved average power control method is presented to regulate the power flow to the super capacitor. Then a dynamic system model is designed using Matlab/Simulink. Furthermore the system simulation and testing results are demonstrating the performance of the control system. The potential cost benefit from energy savings is also analyzed.

TL;DR: In this article, the wavelet variability model (WVM) was used to upscale irradiance measured in Mayaguez, PR to simulate various sizes of PV power plants, and the results showed that ramps will often exceed 10%, even for the largest plants (60MW) that benefit the most from in-plant spatial smoothing, meaning significant amounts of storage will be needed to meet the PREPA requirement.
Abstract: The variability of solar PV power plants has led to some utilities imposing ramp limitations. For example, the Puerto Rico Electric Power Authority (PREPA) includes a 10% of capacity per minute limit on ramp rates produced by PV power plants in its minimum technical requirements for photovoltaic generation projects. However, it is difficult to determine storage requirements to comply with ramp limitations for plants in the planning or construction phase since the variability of the plant output is not known. In this paper, we use the wavelet variability model (WVM) to upscale irradiance measured in Mayaguez, PR to simulate various sizes of PV power plants. The results show that ramps will often exceed 10%, even for the largest plants (60MW) that benefit the most from in-plant spatial smoothing, meaning significant amounts of storage will be needed to meet the PREPA requirement. The results from Puerto Rico are compared to sites in San Diego and Oahu, Hawaii. Significant differences are seen in the ramp rate distributions of the three locations, demonstrating the importance of performing location-specific simulations.

TL;DR: In this paper, a Modular Multilevel Converter based STATCOM with power intensive energy storage (SVC PLUS ES) is proposed to support frequency and voltage support in transmission grids.
Abstract: The developing political and environmental reforms are driving the rapid evolution of today's power systems. There is a steady increase in the electrical energy being fed from renewable energy sources like wind and photovoltaic systems while shutting down large thermal power plants. This trend has a major impact on the performance of the electrical power system networks especially with respect to their dynamic behaviour. Phasing out of existing conventional synchronous generators will adversely affect auxiliary services like voltage control and frequency regulation. The paper discusses one of the solutions to cope with these challenges: the use of Modular Multilevel Converter based STATCOM i.e. SVC PLUS® with power intensive energy storage (SVC PLUS ES) which can significantly contribute to the stable operation of the power system. The successful frequency and voltage support in transmission grids will be presented. Furthermore the design of SVC PLUS ES with supercapacitors as storage technology will be shown.
