Analysis of the Spanish Electricity Market and Proposals for Future Development
KOMUNALNA ENERGETIKA / POWER ENGINERING, 33
Nowadays the electricity is found in any daily activity, while a state can not develop its economic and social potential without a consolidated electricity system. In sense of the liberalized electrical systems, the figure of an electric market becomes fundamental. This paper shows an overview of the Spanish electricity market, involving its problems and future objectives. Spain as a member of the European Union faces the demands proposed by the European Commission. The European challenge is not an individual challenge for individual member but requires the cooperation of all member states, moving towards an energetically integrated European Union.

Evaluation of Probability-Distribution Models for Wind-Power Forecast Error
KOMUNALNA ENERGETIKA / POWER ENGINERING, 53
This paper discusses different probability-distribution models for wind-power forecast error. Models known from the literature (beta, Weibull, gamma) are discussed along with the models with extended-skew generalized-normal distribution. Furthermore, a versatile model is discussed, which enables analytical calculation of the percentile function; however, it is sensitive to wavelets in the probability distribution. Obtained results show that beta, Weibull and gamma probability distributions do not capture the actual (empirical) one; far more adequate are models with skew generalized-normal probability distribution.
