Electricity system planning with a high penetration of renewable energies
Due to society’s increasingly concern about environmental sustainability, many agreements have been signed in the European Union in the past few years to establish medium- and long-term energy frameworks that point out the main energy transition politics that will be taken by all members. Inspired on these politics, this study tries to find which would be the most efficient thermal power generation park needed to ensure the correct and safe operation of the Spanish Peninsula electricity system in a situation where, by 2030, 80 % of total energy production came from renewable energy sources. To perform this study, demand and generation values of two different years are scaled to 2030. Three scenarios are considered regarding the conventional technologies that constitute the thermal power generation park: nuclear, coal and combined cycle as conventional technologies; coal and combined cycle as conventional technologies; and only combined cycle as conventional technology. In each scenario, an optimization process performed with linprog Matlab function is carried out to find which is the most economically optimum distribution of installed capacities and energy generations shares. Results show that, if 80 % of energy generation comes from renewable energy sources by 2030, total installed capacity of the system will increase significantly due to low capacity factors of renewable technologies, causing a considerably large energy spillage because of the unprogrammable nature of these technologies. In a scenario where nuclear, coal and combined cycle technologies constitute the thermal generation park, it is proven that nuclear technology operating as baseload units and combined cycle technology as peaking units is the economically optimum situation. Because of the huge variations of nuclear technology costs that are found depending on the source checked, its investment cost considered for the study is increased until this technology becomes economically suboptimal to operate. The investment cost that makes it happen is ...
