So far, solar energy has been viewed as only a minor contributor in the energy mixture of the US due to cost and intermittency constraints. However, recent drastic cost reductions in the production of photovoltaics (PV) pave the way for enabling this technology to become cost competitive with fossil fuel energy generation. We show that with the right incentives, cost competitiveness with grid p...

Due to development of the demand increasing of energy around the world and the decline of traditional energy sources in electricity generation the development orientation of power generation has been toward renewable energies. The use of these unfailing and renewable resources requires study substrates and new infrastructure in the transmission and distribution networks. Due to the power instab...

This paper provides a self scheduling tool for price taker Gencos. This methodology is based on Robust Optimization (RO) to deal with the uncertainties of market price values in the dayahead electricity pool market. The Genco is assumed to be the entity who decides about the operating schedules of its thermal units and Compressed Air Energy Storage (CAES) units. The benefits of Genco brought by...

This paper presents a hybrid energy storage system based on Compressed Air Energy Storage (CAES), where the extraction of energy is done within maximum efficiency conditions. As the maximum efficiency conditions impose the level of converted power, an intermittent time-modulated operation mode is applied to the thermodynamic converter to obtain a variable converted power. A smoothly variable ou...

Energy systems play a significant role in harvesting energy from several sources and converting it to the forms needed for applications numerous sectors, e.g., utility, industry, building, transportation. In coming years, storage will key an efficient renewable future; more than does today’s fossil-based economy. There are different strategies storage. Among these strategies, of mechanical via ...

Among the possible solutions for large-scale renewable energy storage, Power-to-Gas (P2G) and Compressed Air Energy Storage (CAES) appear very promising. In this work, P2G an innovative type of CAES based on underwater storage volumes (UW-CAES) are compared from a techno-economic point view, when applied in combination with 48 MWe offshore wind power plant, selecting appropriate location both h...

The key component of Compressed Air Energy Storage (CAES) system is an air compressor/expander. The roundtrip efficiency of this energy storage technology depends greatly on the efficiency of the air compressor/expander. There is a trade off between the thermal efficiency and power density of this component. Different ideas and approaches were introduced and studied in the previous works to imp...

Climate change mitigation will require extensive decarbonization of the electricity sector. This thesis addresses both large-scale wind integration (Papers 1–3) and development of new energy technologies (Paper 4) in service of this goal. Compressed air energy storage (CAES) could be paired with a wind farm to provide firm, dispatchable baseload power, or serve as a peaking plant and capture up...

Abstract The widespread diffusion of renewable energy sources calls for the development high-capacity storage systems as A-CAES (Adiabatic Compressed Air Energy Storage) systems. In this framework, low temperature (100°C–200°C) (LT-ACAES) can assume a key role, avoiding some critical issues connected to operation high ones. paper, two different LT-ACAES configurations are proposed. characterize...
