Duration-Differentiated Services in Electricity [PDF]

open access: yesarXiv, 2014
The integration of renewable sources poses challenges at the operational and economic levels of the power grid. In terms of keeping the balance between supply and demand, the usual scheme of supply following load may not be appropriate for large penetration levels of uncertain and intermittent renewable supply. In this paper, we focus on an alternative

Hard- and software implementation and verification of an Islanded House prototype [PDF]

open access: yes, 2009
: Rising energy prices and the greenhouse effect gave a boost to the innovation of energy saving technologies. One of these technologies is microCHP, a replacement of a boiler producing heat and electricity. We investigated whether it is possible to use a

Collaborative strategy for electric vehicle charging scheduling and route planning

open access: yesIET Smart Grid
Due to varying energy demands and supply levels in different regions, the distribution of power load exhibits an imbalanced state. It contributes to increased power loss and poses a threat to the security constraints of the electrical grid ...

Contra-rotating marine current turbines : single point tethered floating system - stabilty and performance [PDF]

open access: yes, 2009
The Energy Systems Research Unit within the Department of Mechanical Engineering at the University of Strathclyde has developed a novel contra-rotating tidal turbine (CoRMaT). A series of tank and sea tests have led to the development and deployment of a

Equity-aware Load Shedding Optimization [PDF]

open access: yesarXiv
Load shedding is usually the last resort to balance generation and demand to maintain stable operation of the electric grid after major disturbances. Current load-shedding optimization practices focus mainly on the physical optimality of the network power flow.

Grid Capacity Issues with Distributed Generation [PDF]

open access: yes, 2014
Climate change is more evident than ever as reflected in The European union's environmental directives which say that the carbon emission must be reduced by 20% and 20% of the used energy must come from renewable energy sources until 2020.

Optimal Net-Load Balancing in Smart Grids with High PV Penetration

open access: yes, 2018
Mitigating Supply-Demand mismatch is critical for smooth power grid operation. Traditionally, load curtailment techniques such as Demand Response (DR) have been used for this purpose.
