For a discussion among experts on the strategic behaviour of energy companies the position of large power producers in electricity markets in northwestern Europe is investigated. This report describes how power markets in European Member States are restructured due to the liberalisation process and how these markets function.

A genetic algorithm is used to solve an economic dispatch problem. The chromosome contains only the encoding of a normalized incremental cost system. Therefore, the total number of bits of a chromosome is entirely independent of the number of units. In the first case, the transmission line losses are calculated using the Newton-Raphson method and kept constant. In the second case, the transmiss...

In order to develop algorithms that identify power grid vulnerabilities, there is a need to evaluate their performance with real grid topologies. However, due to security reasons, such topologies (and particularly, the locations of the nodes and edges) may not be available. Therefore, we focus on a method for generating test networks with similar characteristics to the real grid. Small-world an...

For this purpose, we simulate an agreement between the government, who pursues political prices (guaranteed prices) as low as possible, and the project sponsor who wants returns (stochastic cash flows) as high as possible. The sponsor...

The recent flurry of writing on Russian politics, nationalism and Alexander Dugin shows the contemptible inability of western savants to apprehend any idea beyond the cliche's of stagnant neoliberalism. Worse, “Russia specialists” in academia are now tripping over themselves trying to “analyze” Dugin and the Eurasianist idea. Bereft of the vocabulary to understand the concept, they merely apply...

Even though the Soviet Union is a large industrial state which bases its economic development on its own mineral fuel resources, it cannot afford to neglect the development of nuclear power, because about 80% of its energy resources are concentrated in eastern regions of the country, while 75% of the population and consumers of power are concentrated in the European part of the USSR. The transp...
