Power network planning considering reliability cost and unerved energy cost

It is necessary for power supply company to increase reliability investment cost in order to improve power supply reliability of distributed network and decrease consumer unserved energy cost on distribution network planning,however,if the power company blindly pursuit power supply reliability,it certainly results in sharp increase of reliability investment cost.In order to pursuit the balance between power supply reliability and reliability cost,this paper considers reliability cost and unserved energy cost,and introduces reliability cost-benefit regressive model with which the company can decides optimum reliability scheme in numerous power distribution network planning schemes.It is convenient and efficient that the model and method can decide best reliability scheme on power distribution network planning with the example.
