In July 2013, the government approved a major overhaul of the Spanish electricity sector to correct existing imbalances that have led to an exponential increase of regulated electricity costs and a huge tariff deficit. The reform addresses the problem of financial sustainability of the sector,...

This study investigates the transformative effect of unscheduled solar PV and wind generation on electricity demand. The motivations for the study are twofold, the poor medium term predictions of electricity demand in the Australian National Electricity Market and the continued rise in peak...

The expansion of wind-generation in the United States poses significant challenges to policy-makers, particularly because wind’s intermittency and unpredictability can exacerbate problems of congestion on a transmission constrained grid. Understanding these issues is necessary if optimal...

Abstract. The credit market collapse and housing-led economic recession beginning in 2007-2008 have resulted in several million distressed homes in the U.S. that are in various stages of delinquency, default, and foreclosure. Over the past three to four years, a number of private equity...

The relationships between energy, the environment, and development are deep and complex. The International Energy Agency has noted that energy is deeply implicated in each of the economic, social and environmental dimensions of human development. Energy services provide an essential input to...

Increasing concerns about global environmental issues have led to the urgent development of green transportation. The enthusiasm of governments should encourage the prosperity of the plug-in hybrid electric vehicles/electric vehicles (PHEVs/EVs) industry in the near future. PHEVs/EVs are not...

Due to the interconnection and active management of Distributed Generation (DG) and Energy Storage Systems (ESSs), the traditional electrical distribution network has become an Active Distribution Network (ADN), posing challenges to the operation optimization of the network. The power supply and...

Wave energy conversion is a clean electric power production technology. During operation there are no emissions in the form of harmful gases. However there are unsolved issues considering environmental impacts such as: electromagnetism; the artificial reef effect and underwater noise....

This paper proposes an improved maximum power point tracking (MPPT) method for wind power systems. The proposed method combines hysteresis control with tip speed ratio (TSR) control using a power coefficient curve. It has fast dynamic characteristics with the TSR control using data obtained from...

The rapidly growing world population and rising consumption of biofuels are increasing demand for both food and biofuels. This exaggerates both food and fuel shortages. Using food crops such as corn grain to produce ethanol raises major nutritional and ethical concerns. Nearly 60% of humans in...
