- A Study on the Methodology to Estimate Marginal System LCOE of Power Sources Under High Penetration of Variable Renewable Energies
抄録
In this paper, we propose a method to estimate the marginal costs of power sources referred to as marginal system LCOE (Levelized Cost of Electricity), that was defined in prior works, using mathematical models. We then applied the method to Japan’s power system in 2030 to estimate the relative competitiveness of power generating technologies under high penetration of variable renewable energies (VRE). In a power generation mix consistent with the Strategic Energy Plan of the government, that was published in 2015, the marginal system LCOE of solar PV, onshore wind, nuclear, coal, and gas power generation change to 19.2 JPY/kWh, 22.3 JPY/kWh, 13.2 JPY/kWh, 13.8 JPY/kWh, and 10.3 JPY/kWh, respectively, from the LCOE of 14.9 JPY/kWh, 19.1 JPY/kWh, 10.3 JPY/kWh, 12.9 JPY/kWh, and 13.4 JPY/kWh, respectively. In a system with a higher share of VRE, the marginal system LCOE of VRE and nuclear power rise further. The analysis implies that marginal system LCOE of VRE may rise because of the inflexibility and the electricity losses caused by energy storage and transmission, highlighting the need to investigate the effects of flexibility options to reduce the marginal system LCOE of VRE.
