| 摘要: |
| 为了维持电网稳定运行、节约调度成本、改善用户的舒适度，在空调负荷的优化调度中提出了以最小削减及最少启停为特征的双层调度策略。沿着负荷最优削减方向，以最小空调削减量为目标，实现空调削减在空间上的优化组合；对于各调控节点下的多台空调，以空调启停数量最少为目标，通过安全开关和调温控制策略的优化组合，满足调控精度的要求。所提双层优化策略在保证电网稳定的同时，有效地降低了空调的削减量，并且在保证调控精度的同时，最大限度地保证了用户的舒适度，降低了调度成本。IEEE 33节点配电网算例的仿真结果验证了所提调度策略的可行性和准确性。 |

| Abstract: |
| In order to maintain the stable operation of power grid, save dispatch cost and improve users’ comfort, a bi-level optimal dispatch strategy with minimum reduction and minimum start-stop number as characteristics is proposed in the optimal dispatch of air-conditioning load. Along the optimal direction of load reduction, the optimal combination of air-conditioning load reduction in space is realized with the minimum air-conditioning reduction as its objective. For the multiple air-conditioners at each control node, their requirements of control accuracy are met through safety switch and temperature control strategy with the minimum start-stop number as the goal. The proposed bi-level optimal strategy not only ensures the stability of power grid, but also effectively reduces the reduction of air-conditioning, and at the same time, ensures the control accuracy, maximizes the users’ comfort and reduces the dispatch cost. Simulative results of IEEE 33-bus distribution network verify the feasibility and accuracy of the proposed dispatch strategy. |
