For load-shifting, the IRR was negative for any community by 2020 and only for an average electricity price equal to 0.194 £/kW h (instead of 0.165 £/kW h as assumed in 2020), the IRR becomes positive for load shifting with Economy 7 in 2020 [16]. Alternatively, CES became a profitable energy option when projected to a hypothetical …

With the increasing penetration of renewable energy in power system, energy storage systems (ESSs) are expected to undertake the responsibility for load shifting, so as to reduce the burden of traditional generators. However, the improper size of an ESS will lead to an undesired cost even cause instability. In order to maximize total profits of hybrid …
The island of Saint Vincent currently supplies about 20 percent of its electricity from hydro, and it is moving to develop its geothermal resources, with drilling expected to begin early this year, according to Ellsworth Dacon, Director of Energy in the …
Sometimes called "load shedding," peak shaving is a strategy for avoiding peak demand charges by quickly reducing power consumption during a demand interval. In some cases, peak shaving can be accomplished by switching off equipment with a high energy draw, but it can also be done by utilizing separate power generation equipment, such as on ...
Recent advances in renewable energy generation and the Internet of things (IoT) has urged energy management to enter the era of the Internet of energy (IoE).
