| 摘要: |
| 提出一种热电风电协调调度方法，以热电联产机组和水源热泵作为联合热源，通过联合热源与风电出力的协调控制，减少等效风电出力波动性。该方法以风电出力波动最小为目标，将热源与采暖终端用户之间的供暖热水管道传输距离转化为输送时间，并将其作为热电风电协调调度的关键参量。计算了系统日调峰不足率，该指标反映了风电并网出力随机性对电网日调峰能力的影响，也验证了协调调度方法对减少风电波动和增加风电并网容量的有效性。 |

| Abstract: |
| A method of wind-thermal power combined dispatch is presented，which regards the cogenerations and the centralized water-source heat pumps as the joint heat-source and carries out the coordinated control of joint heat-source and wind power to smooth the fluctuation of wind power output. It takes the minimized fluctuation of wind power output as its object and converts the transmission distance between heat source and heating end-user into the feeding time，which is then used as the key parameter of the combined dispatch. The insufficiency of daily peak-load regulation is calculated to reflect the impact of randomicity of grid-connected wind power output on the peak-load regulation capability of grid，which verifies the effectiveness of the combined dispatch method in reducing wind power fluctuation and increasing grid-connected wind power capacity. |
