The informationally simple approach to incentive regulation applies mechanisms that translate the regulator's objective function into the firm's profit-maximizing objective. These mechanisms come in two forms, one based on subsidies/taxes,the other based on constraints/ price caps. In spite of a...

The purpose of this research was to portray productivity in a larger context than has previously been presented, using system analysis. The result was a single causal loop diagram describing productivity in a work setting. Information on the components affecting productivity and how they...

The present paper shows how cointegration analysis within a multivariate framework may be applied for the estimation of energy demand elasticities in order to account for the non-stationarity of the time series used. The dynamic modelling approach followed is one based on general-to-specific...

For safe and reliable machine operation, maintenance, repair and overhaul (MRO) activities are required. Spare parts demand forecasting and inventory planning, which is an important part of MRO activities, must be accurate to avoid costs because of surplus spare parts or machine downtimes. The...

This paper is on an onshore variable speed wind turbine with doubly fed induction generator and under supervisory control. The control architecture is equipped with an event-based supervisor for the supervision level and fuzzy proportional integral or discrete adaptive linear quadratic as...

The paper presents an economic cost evaluation on the feasibility of offshore wind turbine (OWT) farms development in Nigeria, using a 500 MW OWT farm as an incident study. A developed model was used to evaluate the economic cost of the OWTs at different phases of the project. Additionally, the...

This paper presents a hybrid wind generation with a doubly-fed induction generator (DFIG) and a permanent magnet synchronous machine (PMSM). The study analyzes the performances of the two wind systems and assets the stability of the operating parameters in the presence of a grid fault. Both the...

Fault-tolerable capability of Doubly Fed Induction Generator (DFIG) against disturbance occurrence is recognized as Fault Ride-Through (FRT). With quick and accurate compensation potentiality of Dynamic Voltage Restorer (DVR) to retrieve the nominal PCC voltage, DFIG can safely follow its normal...

The research in this paper reveals how organising the innovation ecosystem can enable the achievement of the aim for innovation and competitiveness. The research was conducted from June 2014 to May 2015 using a qualitative deductive approach among operation & maintenance (O&M) actors in offshore...

On 10 June 2011, the district council of Ahrweiler in the north of the federal state of Rhineland-Palatinate in Germany took the decision to meet 100% of the district's electricity needs through renewable energy by 2030. Yet the share of renewable energy in the district's overall electricity...
