Centralized and Decentralized Electricity Markets: Assessment of Operational and Economic Aspects

This paper presents the comparison of decentralized and centralized market settings in terms of economic efficiencies, particularly price signals, and operating aspects. The decentralized dispatch consists of an energy auction separated from a contingency analysis. The centralized setting is the conventional economic dispatch. This comparison includes deterministic and stochastic formulations (source of uncertainty is wind generation) applied on the Swiss power system.
