Supercapacitors are components for energy storage, well dedicated for applications where energy storage can help to the smoothing of strong and short time power solicitations of a distribution network. Those properties are developed for two examples. The f ...
A simultaneous optimization of the design and operation of a district heating, cooling and power generation plant supplying a small stock of residential buildings has been undertaken with regards to cost and CO?2 emissions. The simulation of the plant cons ...
The aim of the paper is the analysis of the dynamic behavior of a thermoelectric power plant equipped with a steam unit and a gas turbine during the early phases ofa black-start-up maneuver for the network restoration. Models of different detail level for ...
Energy storage systems can be considered today as new means to adapt the variations of the power demand to the given level of power generation. In the context of the use of Renewable Energies or other distributed power generation, they can be used also as ...
Supercapacitors are new and powerful components for energy storage. Compared with batteries, the amount of energy they can store is low. But, as power sources they have the property to be re-loadable in a few seconds [1][2][3]. In that case, the needed ins ...
In this paper the short term scheduling optimization of a combined cycle power plant is accomplished by exploiting hybrid systems, i.e. systems evolving according to continuous dynamics, discrete dynamics, and logic rules. Discrete features of a power plan ...
Supercapacitors are components for energy storage. Due to their series resistors, the energy efficiency of supercapacitors can be low. In this paper, the unloading of supercapacitors with constant current and power are studied, to identify and take into ac ...
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 inte ...
A new feeding concept for electrical transportation systems is presented, based on supercapacitive energy storage. Supercapacitors are new and powerful components for energy storage. Compared with batteries, the amount of energy they can store is low and d ...
Water diversion for hydroelectric power generation impacts the temperature of mountain streams. Such changes are estimated by using a coupled one-dimensional dead-zone heat balance model. In very steep river sections, the dissipation of kinetic energy is t ...
