Policy | \(( [ \alpha _{a}^{l}, \alpha _{a}^{u} ], [ \alpha _{i}^{l}, \alpha _{i}^{u} ], [ \kappa ^{l}, \kappa ^{u} ], [ u^{l}, u^{u} ] )\) | \(( I_{1}^{\mathrm{peak}}, I_{2}^{\mathrm{peak}} )\) | The associated cost |
|---|---|---|---|
No control | ([0,0],[0,0],[0,0],[0,0]) | (105,5 × 105) | – |
Med control | ([0.2,0.4],[0.1,0.2],[0.2,0.25],[0.25,0.75]) | (104,5 × 105) | 4.5349228133 |
Max control | ([0.4,0.5],[0.25,0.3],[0.25,0.3],[0.75,1]) | (104,5 × 105) | 2.8707575932 |
Mix control | ([0.2,0.4],[0,0.1],[0.2,0.3],[0.7,0.9]) | (104,5 × 105) | 1.9432928849 |
