PHYSICAL DISTRIBUTION MECHANISM OF NETWORK LOSS FOR POWER SYSTEMS

Network loss is one of basic parameters for power systems. Thinking of the electricity market factor, the sources of the loss should be known clearly. So network loss distribution is a key work at this area. Up to now, many methods of network loss allocation are given, but they have to face a same question how to divide a product into two parts as their multipliers proportion. This is a no definition proposition, no solution way, so results of these network loss allocation methods are not correct. In this paper, starting with analyzing the physics essence of network loss, the distribution law is pointed out; the linear power superposition theorem is proposed by the one dimension characteristics of energy. The analytic solutions of sources output power, branches power and branches loss power are described by superposition theorem, the network loss factors caused by sources are given, the relation analytic solution between sources and network losses is advanced. With above results, the network losses linear analysis and calculation theory is established perfectly.
