Wind generation is the most widespread form of renewable energy, with a high degree of penetration in traditional electricity networks. Hence, the influence of wind power generation over the efficient operation of power systems is increasingly complex. This determines the actors playing in the wind energy market to show an increased interest in developing efficient forecasting models for power generated...
The western Danish power system is currently the grid area in the world that has the largest share of wind power in its generation profiles, with more than 20% of its annual consumption generated by wind turbines. In this paper, the western Danish power system, which may represent the future of competitive electricity markets in some ways, is chosen as the studied power system. The relationship between...
The integration of wind resources into power systems entails new challenges at all levels of the electricity industry. In this paper, we discuss critical issues emerging due to the incorporation of wind power suppliers in existing electricity market designs. We discuss the impacts of wind power intermittency and uncertainty on the planning and operation of the system and markets. In particular, we...
This paper provides an overview of forecasting problems and techniques in power system. Available forecasting techniques have been reviewed with the focus on data mining for wind power prediction. This paper also discusses forecasting issues associated with electricity price and load forecasting.
The integration of renewable energy sources (RES) into the electricity grid has become an important challenge for the utilization and control of electric power systems, because of the fluctuating and intermittent behaviour of mainly wind power and photovoltaic (PV) generation. By the beginning of 2009 almost 24,000 MW of wind power and about 6,000 MW of PV were installed in Germany. To integrate these...
Large scale trading of wind power in the electricity markets is constrained by the large imbalance costs associated with the wind power. The present short-term power markets are designed for trading conventional generation. For wind generation to participate in the short-term energy markets, lengthy wind power production forecasts are required. Since the wind power forecasts are never perfect, they...
In their attempt to cut down on greenhouse gas emissions from electricity generation, several countries are committed to install wind power generation up to and beyond the 10-20% penetration mark. However, the large-scale integration of wind power represents a challenge for power system operations planning because wind power (i) cannot be dispatched in the classical sense; and, (ii) its output varies...
The results of investigations to identify and quantify the effects of large scale wind generation on the operation of the New Zealand power system and electricity market are presented. The effects of variability of wind generation output and technological capability of wind generation turbines are considered. The variability of wind generation output, wind generation forecasts and management of large...
We present the current status of wind power in the Netherlands and its future prospects, in particular for the development of offshore wind. An overview is given of the performance of the wind power on land. We briefly discuss the experience with OWEZ, the first offshore wind park commissioned April 2007, and the expectations for Q7, to be completed March 2008. The organization of the energy and imbalance...
Uncertain wind power forecasts is a disadvantage in an electricity market where the majority of the trading is performed several hours before the actual delivery. This paper presents a model which can be used to study how changes in the trading arrangement-in particular changing the delay time between closure of the spot market and the delivery period or changing the imbalance pricing system-would...
