| Abstract_FL | Reasonable use of response characteristics of the adjustable load to realize the source-load-energy storage coordinated scheduling can effectively alleviate the peak regulation pressure brought by the uncer-tainties of new energy resource and load.Based on the new energy resource-load(NER-L)similarity,the response target of adjustable load is established.Based on the correlation coefficient,the NER-L similarity index which can accurately describe the tracking and matching degree of load to new energy resource out-put is established,and the index is introduced into the two-stage optimal scheduling model of source-load-energy storage coordinated peak regulation.The first stage model takes the maximum NER-L correlation coefficient as the objective to determine the response power of adjustable load in each period and obtain the optimal power grid load.The second stage model takes the minimum abandoned wind and photovoltaic power and the lowest peak regulation cost as the objectives to optimize the output of thermal power units and energy storages.Taking IEEE 30-bus system as an example,the NER-L similarity,net load peak-valley difference,system peak regulation economy and abandoned power of new energy resource are calculated and analyzed,and the results verify the effectiveness of the proposed model. |
