Embodiment 1
[0083] This embodiment takes the peak shaving process of an industrial park as an example to describe the interaction method described in the present invention in detail.
[0084] According to the load forecast of the distribution network under its jurisdiction, the dispatch management center issues peak-shaving instructions to the park operators in advance, stipulating the upper limit of the park's load usage. Each user in the park reports electricity / heat load information to the operator according to its own energy consumption. After the operator information is summarized, it is judged whether intraday interaction needs to be started on the basis of considering the shiftable load.
[0085] If it needs to be started, the operator will issue a load reduction demand to the user according to the peak shaving instruction, that is, the electric load to be reduced, the thermal load to be increased (corresponding to the electric load to be reduced), and the electric load to be incre...

The invention discloses an interaction method of adjustable and controllable resources for peak regulation auxiliary service. The adjustable and controllable resources comprise a translational load, a transferable load, an interruptible load and thermoelectric energy. The interaction method comprises a day-ahead interaction stage, an intra-day invitation stage and a settlement stage. The day-ahead interaction stage comprises agreement signing, day-ahead bidding and CHP thermoelectric interaction; the intra-day invitation stage supplements the load gap of the day-ahead interaction stage; and in the settlement stage, an operator carries out compensation or punishment according to the specific condition of the calling capacity of the adjustable and controllable resources of the user. According to the interaction method disclosed by the invention, multiple energy consumption characteristics of multiple subjects and adjustable and controllable resources are fully considered, the motivation is high, the flexibility is high, the sustainability is good, and the user acceptability and the operability are considered.
Description
technical field [0001] The invention relates to the field of peak-shaving auxiliary services in electric power systems, in particular to an interactive method for adjustable resources oriented to peak-shaving auxiliary services. Background technique [0002] As the proportion of new energy power generation in my country continues to increase, the power system's requirements for flexibility are also increasing. However, the output of new energy fluctuates greatly, which makes the changes of the upper and lower output of the power grid system become frequent. With the increase in the grid-connected scale of new energy, the compensation model and strength of the original peak-shaving auxiliary service plan can no longer meet the needs of power grid operation, and the problem of insufficient power system adjustment methods has become more and more prominent. Due to the advancement of smart grid technology and metering infrastructure, the flexibility of adjustable resources on t...
