Power generation plan method considering network loss sharing under power market environment containing bilateral transaction

Abstract

The invention relates to a power generation plan method considering network loss sharing under a power market environment containing bilateral transaction, belonging to the technical field of power systems. The power generation planning method comprises the following steps of: network loss sharing among power grid users; network loss sharing of a power generation side; network loss sharing of a power utilization side; and a day-ahead power generation plan, i.e. solving the problem of the unit combination of power generators by taking a running cost (fuel cost + starting cost + transmission cost) minimum as a target function to make the day-ahead power generation plan. The invention also provides a method of the network loss sharing between the power grid users (the power generation side and the power utilization side). The invention can realize a method for making reasonable and apparent network loss sharing in the power market containing the bilateral transaction, enhance the economical efficiency of the unit combination of the power generators, solve the problem of the network loss sharing during the synchronization of the distributed power generation of new energy and provide a unit combination method for making the reasonable and effective day-ahead power generation plan.

Description

technical field The invention relates to a network loss apportionment method among power grid users under an electric power market environment and a day-ahead power generation planning method based on network loss apportionment and transmission costs, and belongs to the technical field of electric power systems. Background technique In the deregulated power market environment, a variety of power trading models will exist. Bilateral trading mechanism is one. This transaction is based on a bilateral contract, and the transaction volume and price are mutually agreed upon by both parties to the transaction. In electricity market transactions, although the costs related to network loss account for only a small part of the total cost, they have a great impact on power transactions and grid users. Who should share how much network loss? is an important issue. However, due to the nonlinear characteristics of the network loss, it is difficult to allocate the network loss accuratel...

In electricity market transactions, although the costs related to network loss account for only a small part of the total cost, they have a great impact on power transactions and grid users. Who should share how much network loss? is an important issue

However, due to the nonlinear characteristics of the network loss, it is difficult to allocate the network loss accurately among the grid users theoretically.
