摘要
The flexibility of fossil-fired power plants is a key element for effective an increased utilization of renewable energy in the sectors power generation, district heating and process heat. Fossil fired power plants are thermal power plants which are coal, oil or gas-fired. A major advantage of gas-fired power stations is its greater operating flexibility, compared with typically baseload designed coal units. In order to reach the vision of a net-zero CO2 emissions world, the expansion of renewable energies is being globally driven forward. The electricity production costs of renewable energies continue to fall because of the competition-oriented calls for tenders, subsidies and feed-in tariffs, and in some cases are already lower than those of conventional power plants. However, renewable energies, especially from solar and wind, shows time depend (seasonally, daily and hourly) flux variations, which does not enable a renewable system to provide energy according to the demand profile of specific users. The most important strategies to overcome this problem are the expansion of the electricity grid and the flexibility of thermal power plants.
