摘要
将基于安全域的电力系统有功定价模型用于拟并网的风电场装机容量和风电场位置的论证中。采用按小时的平均日发电曲线表示风电场的运行约束,并通过比例因子来反映负荷随时间的变化。由于模型中计及了线路热稳定约束和暂态稳定约束,使风电场装机容量和风电场位置对市场价格、发电成本和安全成本影响的分析结果更符合实际。新英格兰10机39节点系统的示例表明,所得的影响分析结果可辅助电网规划人员就风电上网问题做出科学的评估。
The active power pricing model of power system based on the security region is applied to the feasibility study of wind farm location and its capacity. The hourly averaged daily generation curve is used to express the wind farm operation constraints, and the load changes over time are reflected through the scaling factors. Due to the consideration of line thermal stability constraints and transient stability constraints in the model, the impact analysis of location and capacity of wind farm on the market price and generation cost as well as security cost is more in line with the actual results.The studies on New Zealand 10-machine-39-bus system show that the method can help power system planners assess the integration of wind farm more scientifically.
