Description
Summary:In accordance with the Korean 2050 carbon neutrality scenarios, renewable energy accounts for 70.8 % and 60.9 % of the total future electricity production in scenarios A and B, respectively. However, renewable energy is relatively more uncontrollable than other generators, such as gas turbines and power plants, and this condition can lead to grid instability, including electricity waste and blackouts. Here, we analyzed the issues by designing and simulating a South Korean energy supply and demand system. Uncontrollable renewable energy causes a mismatch between power supply and demand. We resolved this issue by increasing the capacity of controllable generators, ultimately resulting in unwanted excess energy generation of 302 TWh and 281 TWh for Scenarios A and B, respectively. Therefore, an energy storage system (ESS), including a battery and electrolysis facility, was added to stabilize the total electrical grid. A stabilized electrical grid provides economic benefits, such as reduced levelized cost of electricity and net present cost, particularly by the battery ESS. Electrolysis can generate hydrogen to be used as a fuel of controllable energy, increasing the stability of the total grid by reducing excess energy more practically than the battery ESS does.
