T1 Efectos de una alta penetración de energías renovables en el sistema eléctrico
A1 Bueno Lorenzo, Míriam
AB The increased share of renewable energies has changed both power system functioningand conventional plants operation. With regard to the latter, power plants using fuelhave change their operation mode to accommodate to the variability and partial predictabilityof renewable energy sources. This fact increases the operation costs of theconventional plants. Besides, market prices behaviour will experience changes, such asthe decrease of average prices and the increase of their variability. The positive e ectsof an increased renewable installed capacity are also assessed. Furthermore, in countrieswith abundant solar resource, studying the e ects of a higher share of renewable energysources on the generation mix is necessary, including a high portion of photovoltaic andsolar thermal energy in the generation portfolio. Therefore, a model of the concentratedsolar power generators has been developed in this work. The results of the thermoelectricmodel supplies the annual production of this technology, which has been integrated inthe generation schedule model. To analyse the impact of the future con guration of thegeneration mix on the power system, a model of unit commitment has been employed.It includes the characteristics and installed capacity of the generators using fuel and theestimation of the future production series of renewable energies. The results discussioncontains an analysis of some relevant characteristics of the future power system behaviour,such as, daily market prices, yearly production by technology, capacity factors of the differenttechnologies, wind spilled energy, ratio of demand coverage coming from renewablesources, hourly variation of the energy supplied by hydro, coal, and natural gas powerplants, greenhouse emissions and operation costs.
