BASTIDAS, Sandra  and  ARCOS, Hugo. Economic Dispatch of the Hybrid System of the Santa Cruz and Baltra Islands Incorporating the Randomness of Power of the Eolic and Solar Photovoltaic Systems. Revista Técnica energía [online]. 2019, vol.16, n.1, pp.1-7. ISSN 2602-8492.  https://doi.org/10.37116/revistaenergia.v16.n1.2019.329.

In the present work a model is developed for the realization of the Economic Dispatch in the short term (24 hours of a typical day) of the Baltra and Santa Cruz Island Hybrid System (thermal, wind and solar photovoltaic generation) located in Galápagos.

Due to the randomness that the wind and solar resource presents (random variables), in order to introduce the Power of these renewable systems within the problem of the Economic Dispatch, a treatment is made to the random variables, using Montecarlo Simulations Techniques, for which, there is a three years of historical data base.

For the Economic Dispatch is considered that the renewable sources deliver all the power determined in the treatment, but as it isn’t enough to supply the load of hybrid system, the missing power is complemented by thermal generation. In the current work the storage systems or battery bank is not modeled.

To perform Economic Dispatch of the thermal generation, the optimal power flows are used, that look for minimizing the generation operating costs, using the interior point method.

Keywords : Montecarlo; random variable; probability density function s; root mean square error; optimal power flow.
