| 摘要: |
| 为了体现风电的环境价值，建立电力市场环境下大规模异步风电并网电力系统动态最优潮流模型。首先计算风电场功率输出期望值，在此基础上，引入基于风电场极限穿透功率的风电弃风运行惩罚成本(WAOPC)以处理弃风行为；然后考虑火电机组的排污特性，并用名义环境补偿成本(NECC)来量化火电环境成本；最后引入风电备用成本(RCCC)来处理随着系统风电穿透水平增加而引起的系统二次备用上升。仿真表明，所建立的模型既考虑了电能生产所产生的环境污染和资源消耗等外部成本，同时也计及了因弃风行为造成的风电损失，合理地反映了以风电能源形式的电能价值。 |

| Abstract: |
| In order to reflect the wind-power environmental value, a dynamic optimal power-flow model is established for the power system integrated with large-scale asynchronous wind-power generation units under the electricity market environment. The power-output expectation of wind farm is calculated first, based on which, WAOPC(Wind Abandonment Operation Penalty Cost) is introduced based on the wind farm penetration limit to deal with the behaviour of wind-power curtailment. The pollution discharge characteristics of thermal power units are then considered, based on which, NECC(Nominal Environmental Compensation Cost) is adopted to quantify the thermal-power environmental cost. RCCC(Reserve Capacity Compensation Cost) is introduced in the end to deal with the increase of system secondary reserve due to the raise of wind-power penetration level. The simulative results show that, the model considers not only the external costs of energy production, such as environmental pollution, resource consumption, etc.,but also the loss of wind-power curtailment, reasonably reflecting the energy value of wind power. |
