Recently, power system becomes more complex. Generation plants are located far from the load center. Moreover, load shape becomes more sharp. Difference between peak and off-peak demand is spreaded more and more.
On the other hand, introduction of economical dispersed generators near load center and time of use pricing are considered. If many dispersed generation plants will be operated and time of use pricing will be introduced, above problem may be cleared.
In this paper, the effect of introduction of dispersed generation and time of use pricing as new pricing strategy at one area is studied. As a result, since the introduction of too many dispersed generation plants makes load factor lower, total surplus in the area decreases. However, in case if time of use pricing is introduced, the load factor becomes higher. Total surplus in the area can be increased.
