| 요약2 | This paper presents optimal electricity power operation compared with different meta heuristic methods in of micro-grid. We also evaluate operation price using the selected optimization method based on subsidy system of DERs (distributed energy resources). The meta-heuristic methods show that the averaged electricity load are reduced 6,066 kWh per month (▼9.45%) and electricity price are saved 778,000 KRW per month (▼11.78%) compared to original operation method without DERs. Among them, the MILP (Mixed-integer Linear Programming) method shows not only outperformed optimization performance but also can reduce operation price of 2% compared with other methods. We then evaluate the operation price applying subsidy system of DERs based on MILP method. The results show that 2,207,000 KRW per month (▼30.31%) of total operation price can saved by using MILPS (Mixed-integer Linear Programming with subsidy) compared with MILP method for a month. Finally, MILPS method can reduce price savings of 3,037,000 KRW (▼37.45%) compared with the original operation method for a month. |
