【摘要】：在消纳新能源实时波动功率时,负荷聚合商的用电风险特性可能带来用电高峰缺电、频率失稳及降低电能质量等威胁,甚至影响微网的可靠运行。以负荷聚合商的协调控制为手段,建立基于调度优先权的独立微网双层实时调度模型。在宏观层,根据负荷聚合商的用电风险特性,建立用电贡献度和用电置信度评价指标量化风险,分别从主、客观两个角度结合应用层次分析法和熵权法,综合评估各指标权重确定调度优先权,微网运营商即可制定满足微网具体要求的各负荷聚合商实时调度计划。在微观层,为降低消纳宏观层实时波动功率时负荷聚合商响应的不确定性,针对负荷聚合商工作时间和用户经济水平的差异,分别提出可中断时间补偿度和消纳分摊权,建立总负荷聚合商利益最大化优化消纳分摊策略。最后,以某地区的实际微网为例,分析验证了模型的科学性和有效性。
[Abstract]:When absorbing the real time fluctuating power of new energy sources, the power risk characteristics of load aggregators may bring about the threats of peak power shortage, frequency instability and the reduction of power quality, and even affect the reliable operation of microgrids. Based on the coordinated control of load aggregators, a two-layer real-time scheduling model of independent microgrid based on scheduling priority is established. At the macro level, according to the characteristics of electricity risk of load aggregator, the evaluation index of contribution degree and confidence degree of power consumption is established to quantify the risk. The AHP and entropy method are applied from subjective and objective angles, respectively. By synthetically evaluating the weights of each index to determine the scheduling priority, micronetwork operators can formulate real-time scheduling plans for each load aggregator to meet the specific requirements of the micro-network. In order to reduce the uncertainty of load aggregation quotient response when the real time fluctuation power of load aggregator is reduced, the interruptible time compensation degree and the consumption allocation right are put forward in view of the difference of load aggregator's working time and user's economic level. Establish the optimal strategy of total load aggregator profit maximization. Finally, taking the actual microgrid in a certain area as an example, the scientific and validity of the model are analyzed and verified.
