The invention relates to a virtual power plant system for carrying out peak clipping and valley filling services in batches. Member application, auditing and configuration of a virtual power plant arerealized in an earlier-stage preparation link, and event initiation preparation, process monitoring supervision and event analysis and settlement under specific peak clipping and valley filling requirements are realized in an event response link. The cloud platform publishes newly established demand response events online through a new response event module, an event publishing module, an event preparation module and an invitation reply module which are arranged, and initiates batch invitation to the selected virtual power plant members based on a preset response plan; and the cloud platformcounts event participation willingness and plan response amount according to feedback provided to the cloud platform by the invited members within the specified time. Through a complete marketizationmeans, the whole process of batch invitation, process monitoring and event settlement is online, the user is guided to participate voluntarily, the active demand response of the user-side load is realized, and the safety and economic operation level of the power grid is improved through large-scale demand response.
