摘要
Abstract
It is unfair for gencos in an electricity market that is open at generation side and adopts direct bidding by generation bidding while the influence of transmission loss on bidding transaction. The physical distribution of power flow in power grid is analyzed and an analytical expression for the relation of nodal load and network loss to power component supplied by power sources is given. By means of power decomposition the transmitted power from power source along the supply path and its power loss in the supply path can be solved; following the principle of cost flow conservation and starting at power source node, the power prices at transmission nodes are calculated, then a generation bidding model considering the modification of network loss is built. It is proposed that the generation bidding should be based on power plant but not based on generation unit, and a day-ahead market transaction model is built by plant bidding considering the modification of network loss. The feasibility and effectiveness of the proposed model are verified by calculation results of improved IEEE 14-bus system.关键词
