Parameter | Formulation |
|---|---|
\({\widehat{B}}_{u,\mathrm{GF}}\) | \(B_{{u,{\text{GF}}}} - B_{{p,{\text{GF}}}}\) |
\({\widehat{I}}_{u}^{s}\) | \(I_{u}^{s} + B_{{p,{\text{GF}}}} - B_{{{\text{GF}}}}^{S}\) |
\(b_{u,i}^{{}}\) | \((b_{u,i} - B_{{u,{\text{IF}}}} + \lambda_{i} N_{u,i}^{q} ) - (b_{p,i} - B_{{p{\text{,IF}}}} + \lambda_{i} N_{p,i}^{q} )\) |
