The paper presents a new wind power generation planning framework by considering the reactive power capabilities of generators. The motivation is to maximize the utilization of renewable power hosting capacity without violating the security constraints of distribution networks. The objective is to maximize the net present value of the investment considering the cost of grid energy transaction, initial...
this study evaluates the impact of wind power generation connected to distribution systems. Three load profiles (residential, commercial and industrial) connected to the distribution network were analyzed considering the impact on voltage levels for different wind speeds and wind generator control strategies. The wind generator model is based on doubly fed induction generator (DFIG) and were developed...
Due to the benefits of distributed generation (DG), in particular wind DG on a power system, researches on its optimal allocation increased. However, most of these studies failed to incorporate the stochastic nature of wind which could lead to an erroneous result for not considering uncertainties. To address these uncertainties, different wind DG models are used. This paper compares how optimal allocation...
Wind generators are increasingly being integrated into high voltage transmission systems as well as low or medium voltage distribution systems. The increased penetration of wind generators into power grid may significantly change the system voltage profile, losses and other operating characteristics. This paper investigates the effects of wind generators on voltage profile and losses of a distribution...
From 2003 through 2008, the Utility Wind Integration Group (UWIG) monitored the performance of one 950 kW turbine located in Palmdale, CA, one 50 kW turbine located in Calverton, NY, and four 50 kW turbines located in Selawik, AK under actual operating conditions. Complete data are available through the UWIG website, with views of real-time and historical data and events. In this paper, we (1) inform...
This paper proposes a novel integration of doubly fed induction generator (DFIG)-based wind farms within microgrids. The main and probably the best feature of this method is that the voltage and frequency of the microgrid are controlled by the wind generators through droop characteristics. Therefore, this control structure is quite suitable for cases where the wind generators supply significant part...
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'...
In this paper a microgrid consisting of wind turbine generators, aqua electrolyzer, fuel cell and diesel generator is examined. The wind generator is controlled using a constant power strategy, to reduce the power fluctuation due to wind speed variations. On the other hand power produced from all the other distributed generation (DG) sources are regulated by simple PI controllers. As the balance between...
