Joint Source-Storage-Grid Planning Method Considering Coupling Relationship of Wind Power Curtailment Events
Insufficient flexibility of power system and transmission congestion are two fundamental reasons for wind power curtailment
and they have a certain coupling relationship in time sequence. From the perspective of time-sharing reuse of energy storage
this paper uses the coupling relationship between wind power curtailment events to solve the problem of insufficient peak shaving and transmission congestion at the same time by configuring energy storage
and proposes a joint source-storage-grid planning method considering the coupling relationship of wind power curtailment events. Firstly
the generation mechanism of wind power curtailment due to insufficient peak regulation
blocking wind power curtailment and their coupling relationship are analyzed. Then
the influence of energy storage configuration on the installed capacity planning of source-side conventional units and the configuration of grid-side transmission capacity is analyzed. Secondly
this paper constructs a joint source-storage-grid planning model considering the conventional thermal power installation investment cost
energy storage investment cost
wind power curtailment penalty cost and transmission line expansion cost
and gives the solving process of the model. Finally
the effectiveness and feasibility of the proposed method are verified by the simulation of the transmission engineering system of a local power grid in Northeast China and Garver-6 node system.
