This paper presents the analysis of a distribution system subject to reconfiguration with high wind penetration over a period of 24 hours. In order to meet this objective, the reconfiguration problem is solved through mixed integer linear programming considering the stochasticity of the variables, where the balance between load and generation has to be satisfied at the lowest cost in each period....
The expansion and diversification of the Uruguayan energetic infrastructure, with significant penetration of renewable sources is leading to structural changes in the power system, in both transmission and distribution subsystems. These changes impact in the operation criteria and also in the power system protection.
With the continuous effort of exploiting wind energy, a higher penetration of wind power will be integrated into networks in the form of distributed generation. In order to well plan the integration of wind power and the network, the randomness of wind power as well as its influence to the whole distribution networks should be considered. As a result, traditional optimal planning approach for distribution...
Nowadays, the implementation of environmentally-friendly and uncontrollable primary energy sources in the electrical power system production is increasing, introducing abatement in generation dispatchability. The incorporation of high levels of small-scale non-dispatchable distributed generation leads to the transition from the traditional 'vertical' power system structure to a 'horizontally-operated'...
This paper presents a methodology for integrated reliability evaluation of distribution and sub-transmission systems with the presence of distributed generation (DG) based on different energy sources. The methodology considers the possibility of DG connection at the High Voltage (HV) and Medium Voltage (MV) buses of the distribution substation, as well as along the MV distribution network. The uncertainty...
Around the world, a rapidly increasing growth of distributed energy resources (DER) based on renewable energy sources (RES) can be observed. This is due to the increase in energy demand combined with restriction in building new large scale power plants and a search for carbon-free technologies for energy production. Among the existing renewable distributed generation technologies, wind turbines (WT)...
