In this paper, the point estimate method is applied to account for the uncertainties that affect the evaluation of the steady state operating conditions of an unbalanced three-phase power system in the presence of wind farms. The accuracy of the proposed technique is tested on the three-phase unbalanced IEEE 34-bus test system adequately modified to take into account the presence of wind farms; the...
In this paper, the problem of the use of dispersed generation (DG) for providing ancillary services in electrical distribution systems is addressed. Fuel cell-based, photovoltaic cell-based, and wind generation systems are connected to the distribution network through power electronic interfaces, each with a proper storage system for the optimal grid operation. Thanks also to the storage system, the...
A probabilistic method is proposed to take into account the uncertainties of loads and wind production in electrical unbalanced distribution systems. The proposed method is based on Monte-Carlo simulation applied to the nonlinear three-phase load flow equations including wind farms, thereby taking into account all load and line unbalances that can characterise the distribution systems. The method...
Nowadays the need for more flexible electric systems, the changing in the regulatory and economic scenarios, the importance of harnessing energy savings and minimising environmental impact have been providing the impetus for the development of a new distribution system into which embedded generation with wind farms is predicted to play a key role. While several advantages result from wind farms presence...
