This work studied the method of planning medium voltage distribution network based on modified ant colony optimization algorithms and designed a rational planning scheme to reduce investment and operation cost.The method en-tails saliently a mathematical model of medium voltage DB planning whose constraints and objectives are load demands + power flow limitations and minimum investment and operation cost,respectively,and an ant colony optimization algorithm modified by transforming the state transition criterion.Experiments proved that the proposed method,by plan-ning DB based on the mathematical model and the modified algorithm,can keep the load of medium voltage DB within a rational range,thereby reducing investment and operation cost.
