Abstract Due to the rapid growth and the volatility of wind power, wind power accommodation becomes much more challenging. As combined cooling, heating and power (CCHP)-based microgrids (MGs) operators(CMGOs) can schedule the local multi-energy (cooling, heating and power) generation, storage and implement integrated demand response to accommodate abandoned wind power. In this paper, an incentive mechanism is proposed to facilitate wind power accommodation trading.In themechanism, a wind power supplier (WPS) organizes many CMGOs to participate in the wind power accommodation trading. Besides, a novel index termed as contribution rate, is proposed to evaluate the participants’ contributions to the wind power accommodation trading. Then, based on participants'contribution rate the benefits allocation mechanism is designed. As different CMGOs tend to make decisions independently, it is impractical to solve the optimization problem in a centralized method. A distributed method is proposed to solve the optimization problem using the alternating direction method of multipliers decomposition technique. The simulation results demonstrate that the abandoned wind power is accommodated by CMGOs well, and both WPS and CMGOs get benefits from the wind power accommodation trading according to their contribution rates.

考虑贡献率的基于CCHP的风电消纳微电网激励机制设计

摘要 由于风电的快速增长和波动性，风电消纳变得更具挑战性。由于基于冷热电联产 (CCHP) 的微电网 (MG) 运营商 (CMGO) 可以调度本地多能源（冷、热和电）的发电、存储和实施综合需求响应，以适应废弃的风电。本文提出了一种促进风电消纳交易的激励机制。在该机制中，风电供应商（WPS）组织多个CMGO参与风电消纳交易。此外，提出了一个新的指标，称为贡献率，用于评估参与者对风电消纳交易的贡献。然后，基于参与者的贡献率设计了利益分配机制。由于不同的CMGO倾向于独立决策，集中解决优化问题是不切实际的。利用乘法器分解技术的交替方向法，提出了一种分布式方法来解决优化问题。仿真结果表明，CMGOs很好地容纳了废弃的风电，WPS和CMGOs都根据各自的贡献率从风电容纳交易中获益。
