Abstract

The share of dispersed generation, especially wind, hydro, solar and biomass powers is increasing in Europe partly because of a growing environmental concern and some reliability needs that some consumer have. However, the growth is limited by the market rules and the technical possibilities. This work shows those limits and examines the effect Demand-Side Management (DSM) can have on them. DSM consists in varying the consumers' consumption according to the situation. The work shows what possibilities already exist for DSM schemes, which ones are already in place and which ones are studied. The accent is put on how DSM could alleviate the problems in the electricity networks that are due to distributed generation (DG). The result is that the effect of DSM on DG-related problems has a rather small potential. However, the effect of DSM on the network is sometimes good enough to justify the investment as that is now the case in New York for instance. The work starts with a presentation of the DG main technologies, of the DSM schemes, of the markets and very shortly of the network. Only after is studied what effects they have on each other and how to combine them.
