STUDY ON THE DEVELOPMENT STATUS AND TREND OF DISTRIBUTED POWER IN CHINA

Most of the electric power in China is from coal combustion power station, so that the pressure ofenvironmental protection is high. At the same time, there is big difference of development between EastChina and West China, which brings some difficulties to centralized power delivering. Because of itscharacteristics, distributed power (DP) can slow down these contradictions, so it develops quickly inChina. The DP is mainly used in special situations, temporary electric power consuming,power-peaking adjustment and improvement of safety of the power network, and it also can be a goodpower supply method for some developing areas in West China, where centralized power supplies arenot suitable. On the other hand, the cost of the DP is high, and the introduction of DP may inducevoltage fluctuation of the main power network and relative problems. These issues need to be furtherstudied. With the improvement of the DP technologies, devices, and efficiency, its application rangewill extend to various situations. DP will not only act as an important supplement of the traditionalelectric power supply mode, but also hold important position in the field of comprehensive energyapplications, and it will become an important developing direction.
