An Interactive Dispatching strategy for Virtual Power Plants Based on Multi-Energy Coordination and Demand Side Bidding

摘要

VPP (Virtual Power Plant) plays an increasingly important role in ancillary service market as reserve provider. This paper studies the VPP with flexible load and CCHP (Combined Heating, Cooling and Power), and proposes the interactive dispatching strategy based on demand side bidding and multi-energy coordination, which could achieve certain load curtailment plan by taking advantage of CCHP and interruptible load. Demand side bidding could significantly decrease interruptible load cost; the relationship between the demands for electric, heating and cooling is considered to achieve multi-energy demand response and prevent overly high bids. The case study proves that this strategy could significantly decrease the overall costs of VPP, while fulfilling the load reduction requirement.
