| Abstract |
Jeju Island, Republic of Korea, is the most active region for electric vehicles and renewable energy sources. However, in Jeju Island, the problems of wasted batteries from electric vehicles and the curtailment of renewable energy output already appeared. To solve this problem, there is a method to install and operate SLB(Second life battery from electric vehicle) with solar power generation. From this perspective, this paper proposes the optimal capacity calculation and maximum price calculation methods for ESS(Energy storage system) based SLB applied to solar power generation. The optimal capacity and maximum price of the SLB are derived based on the capacity and price of the new ESS. The proposed method was simulated based on the weather data actually measured in the Jeju area using the MATLAB program. As a result of the simulation, the optimal capacity of SLB was calculated as 389kWh for 200kW PV farm. To Install calculated SLB, 354SLB modules were required and its maximum price was decided as 132,000KRW. |
