Source-Load-Storage Coordination-considered Optimization of Distributed Renewable Generation Planning in Elastic Distribution Networks
Conventional distributed power allocation optimization methods focus mainly on network loss cost optimization and are inadequate in considering the elastic demand of distribution networks,which affects the economy of source plan-ning optimization.Therefore the present study tried to design a source-loade-storage coordination-considered method of op-timizing the planning of distributed renewable generations.The main work entailed the construction of uncertainty sets of source,load and storage of distributed generations,and the determination of source-load-storage unbalanced power ac-cording to the difference between output power and load power of the renewable generation to ensure the subsequent plan-ning optimization utility.Based on source-load-storage coordination,the optimization model was established and the deci-sion variables of distributed generations were adjusted to cope with source-load-storage uncertainty and meet the require-ment of source planning.The design was expected to optimize the maximum charge and discharge power,compensate for the power imbalance of renewable generations,and realize economic operation of power supply.The comparison experi-ment verifies the effectiveness and potential practicability of the proposed method.
