| Abstract | MW power flow tracing was invented to assess the extent of network usage by the participants so as to allocate the transmission charges and losses. MW power tracing, a post-facto analysis of power flow solution, is amenable to multiple solutions. This implies multiplicity of solution space of cost and loss allocation problem. Existing tracing methods enforce a 'proportionate sharing rule' to arrive at a solution. Case studies indicate that with such a sharing rule, extent of network usage predicted for large and distant loads can be much higher than the postage stamp or pro-rata allocation. To alleviate this problem, we suggest a new paradigm of MW power tracing algorithms wherein, we exploit the multiplicity of solution space so as to achieve a fair and equitable distribution of losses among the participants. We show that real power tracing represents a generic class of multi-commodity network flow problems and can be formulated as a linear constrained optimization problem. We propose a tracing compliant modified postage stamp allocation method which computes a traceable solution that minimizes deviation from the postage stamp allocation of losses. Results on practical data of central transmission utility of Western Regional Grid of India demonstrate the claims. |
