Synergetic optimization strategy of demand response and TCSC under spot market
In order to cope with the phenomenon of transmission blocking caused by the execution of power dispatch using price as the signal,and reduce the increased generation cost and power consumption cost caused by the blocking,a synergetic optimization strategy of demand response and thyristor controlled series compensator(TCSC) is proposed. A bi⁃layer nonlinear model is constructed considering the interest demand of load serving entities and system operator,the upper layer determines the demand response scheme for the purpose of reducing the electricity consumption cost,and the lower layer determines the unit output,the operating parameters of TCSC,and the marginal tariffs of each node. The PSA⁃KKT solving method is proposed combing proportional⁃integral⁃derivative⁃based search algorithm(PSA) and Karush⁃Kuhn⁃Tucker(KKT)condition,which reduces the model nonlinearity. The problem model is transformed into a mixed⁃integer li-near model by the large M method,and solved by CPLEX. The simulation results of IEEE 24⁃node system show that the strategy can effectively alleviate the phenomenon of transmission blocking and reduce the power consumption and generation costs,and the PSA⁃KKT method has faster convergence speed and more accurate calculation results compared with the traditional methods.
