Analytical Formulae and Algorithm for Substation Optimization Planning with Interruption Cost Being Considered
Substation optimization planning is the key to avoid wasteful investment.In the absence of detailed data,new analytical formulae are presented for the substation optimization planning with the customer interruption cost being considered,based on the assumption of uniform load distribution.In the simplified models of analytical formulae,the total cost is represented by a function of substation number,and the line cost is calculated according to the estimated number and power supply radius of feeders.Based on the extreme value method,an algorithm is proposed for the single-stage substation optimization planning.Through the application of proposed models and algorithm to a real distribution network,it is shown that the larger the proportion of cable circuits is or the higher the customer interruption cost is,the greater the optimal number of substations is and the smaller the substation capacity is,and larger load density corresponds to bigger substation capacity and number.
