TL;DR: This work introduces a new open-source electricity planning model--Switch--that identifies the least-cost strategy for using renewable and conventional generators and transmission in a large power system over a multidecade period.
Abstract: Wind and solar power are highly variable, so it is it unclear how large a role they can play in future power systems. This work introduces a new open-source electricity planning model—Switch—that i...

TL;DR: In this article, the authors provide a complete analysis of a PV harvesting system for indoor low power applications, the characteristics of a target load, photovoltaic (PV) cell and power conditioning circuit are discussed.
Abstract: Utilization of low power indoor devices such as remote sensors, supervisory and alarm systems, distributed controls, and data transfer system are on steady rise. Due to remote and distributed nature of these systems, it is attractive to avoid using electrical wiring to supply power to them. Primary batteries have been used for this application for many years but they require regular maintenance at usually hard to access places. This paper provides a complete analysis of a PV harvesting system for indoor low power applications. The characteristics of a target load, photovoltaic (PV) cell and power conditioning circuit are discussed. Different choices of energy storage are also explained. Implementation and test results of the system are presented that highlights the practical issues and limitations of the system.

TL;DR: In this article, the authors presented a hybrid FC/battery power system for a low power boat, which consists of the association of a proton exchange membrane fuel cell (PEMFC) and battery bank.
Abstract: All-electric ships are now a standard offering for energy/propulsion systems in boats. In this context, integrating fuel cells (FCs) as power sources in hybrid energy systems can be an interesting solution because of their high efficiency and low emission. The energy management strategy for different power sources has a great influence on the fuel consumption, dynamic performance and service life of these power sources. This paper presents a hybrid FC/battery power system for a low power boat. The hybrid system consists of the association of a proton exchange membrane fuel cell (PEMFC) and battery bank. The mathematical models for the components of the hybrid system are presented. These models are implemented in Matlab/Simulink environment. Simulations allow analyzing the dynamic performance and power allocation according to a typical driving cycle. In this system, an efficient energy management system (EMS) based on operation states is proposed. This EMS strategy determines the operating point of each component of the system in order to maximize the system efficiency. Simulation results validate the adequacy of the hybrid power system and the proposed EMS for real ship driving cycles.
