| 摘要: |
| 多微电网的协调优化与控制是保证多微电网系统高可靠运行的有效途径。提出一种考虑交互功率控制和双边竞价交易策略的多微电网双层优化调度模型。上层以微电网与配电网交互功率和交互功率波动最小化为目标。下层以多微电网系统的综合成本最低为目标，并采取双边竞价交易策略协调多个微电网之间的公平交易和功率分配。通过实际算例验证了该优化模型能够降低多微电网系统与配电网交互功率和交互功率的波动，所设计的交易策略能降低多微电网系统综合成本。 |

| Abstract: |
| Coordinated optimization and control is an effective way to ensure highly reliable operation of the multi-microgrid system. A scheduling model of a multi-microgrid system based on bi-layer optimization with consideration of Point of Common Coupling (PCC) power control and bilateral bidding is proposed. The upper layer aims at minimizing the PCC power and its fluctuation. The lower is to reduce total cost of the multi-microgrid system. In order to coordinate fair dealing and power allocation between the microgrids, a bilateral bidding strategy is adopted. The simulation results demonstrate that the optimization model can reduce the amount and the fluctuation of the PCC power, and the designed bilateral bidding strategy enables reduction of the overall cost of the multi-microgrid system.
