Embodiment Construction

[0022] Further illustrate the invention the following detailed description in conjunction with the accompanying drawings to enable those skilled in the art may be deeper understanding and practice the invention, but merely below, serve to explain the present invention by referring to examples, the present invention is not It defined.

[0023] like figure 1 As shown in a wind and solar power offset dynamic compensation program storage energy management method, comprising the steps of:

[0024] Step 1, similar to the weather forecast the next 24 hours and weather conditions in the past years of historical data to run the new energy, power generation were recently predicted that the next 24 hours to get new energy power generation program, and then depending on the wind speed range corresponding to the intensity forecast the deviation of the next 24 hours of power in the new energy plan deviation estimate, distortion forecast data for 24 hours of planned power integrated over time in...

Abstract

The invention relates to the technical field of new energy power generation, in particular to a wind-solar complementary power plan deviation dynamic compensation energy storage energy management method. The initial charge quantity of the energy storage system designed based on day-ahead wind-solar power generation power dispatching plan deviation compensation is considered from the effective utilization of the capacity of the energy storage system, and the power deviation is fully compensated under the condition that the residual charge state is sufficient to compensate the plan deviation; when the state of charge is insufficient, the compensation limit is properly relaxed within the planned deviation limiting range by combining the load change trend and the new energy grid-connected power generation standard, and the over-charging and over-discharging condition of the energy storage system is avoided; and when the energy storage system is not enough to compensate the power deviation and the deviation is too large, a standby energy storage equipment switching-in mode is adopted. According to the invention, the constraint of the power grid load change factor and the new energy grid-connected power generation admission standard is fully considered, the accuracy requirement of the power dispatching plan is met, the new energy grid-connected power generation capacity is improved, and stable and reliable operation of the power grid is effectively supported.

Description

Technical field [0001] The present invention relates to a technical field of new energy generation, in particular to a wind and solar power offset dynamic compensation program storage energy management method. Background technique [0002] Easing the load growth due to the supply pressure brought new energy to a certain extent, but the unstable power supply grid to increase the difficulty of scheduling fluctuations to a certain extent, the reliability of the power generation plan must be guaranteed. National Energy Board and grid scheduling management departments for new energy grid behavior issued a document specification. In addition, many countries have also raised the international standard for the punishment issue new energy plan are not allowed, which all contributed to the power generation operators to exhaust all the ways to improve the reliability of power generation plans and reports data. New energy generation energy storage system in which the joint almost become the ...
