Double Layer Real-time Scheduling Model of Independent Microgrid Considering Scheduling Priority of Load Aggregators
摘要
Abstract
In accommodating the new energy real-time power fluctuation,the load aggregators' electricity risk characteristics may bring about such threats as peak power shortage,power imbalance due to frequency instability and lowering of electric energy quality and other threats,and even an influence on the reliable operation of the microgrid.In order to improve the real-time confidence of the microgrid electricity strategy,a double real-time scheduling model of independent microgrid based on priority scheduling is created by means of the aggregators'coordinated control and priority scheduling.At the macro layer,the contribution degree and confidence degree of the electricity indexes are defined according to the electrical risk characteristics of load aggregators to quantify the risk.From the perspective of subjective and objective point of view,the comprehensive evaluation of each index is calculated using the analytic hierarchy process and entropy weight method to determine the scheduling priority in accordance with the specific requirements.Microgrid operators can make the real-time scheduling scheme of the load aggregators based on the scheduling priority.At the micro layer,in order to reduce the load aggregators response of uncertainty when real-time power fluctuations are disposed of at the macro layer,the compensation degree for interruptible time and the consumptive contribution weight are put forward respectively considering the differences of the work time and user's economic level in the load aggregators.Finally,simulations on real microgrid show the scientific character and effectiveness of the proposed model.关键词
