The capacity credit of wind power expresses how much ‘conventional’ power can be avoided or replaced by wind power. From data available in the literature, we have designed an analytical formula for the capacity credit based on the penetration level of the wind power in the power system, the...

In the absence of direct sources of greenhouse gas (GHG) emissions (i.e. combustion), other sources of emission become dominant in so-called [`]emission-free' power plants. In this study the indirect GHG emissions, related to construction of nuclear plants, windfarms and photovoltaic plants, are...

In the literature, several methods are being used to evaluate the contribution of wind energy conversion systems in a broader power-generating system. However, not all of them guarantee accurate results. This paper critically reviews several methods used in the literature for such reliability...
