Research on consumption potential of uncertainty photovoltaic generation based on efficiency power plant

As solar with the highest development potential, photovoltaic (PV) generation increases fast in installation and grid connection with continual mature and improvement of relevant technique. However, the inherent uncertainty of PV generation has direct influence on the stable operation and consumption potential of its connected system, and this has become one of the key problems relating to continuous development of power system. In order to study the consumption potential of uncertainty PV generation in the existing power system, this paper first analyzed the characteristics and regulation potential of different efficiency power plants. Then a consumption assessment system of uncertainty generation was developed, which considered the participation of efficiency power plants in system regulation together with the conventional power plants, the equipment control margin and the optimization layout of uncertainty generation. Finally, some effects on the consumption potential of PV generation are studied by simulating in the test system, which include the node voltage compensation, efficiency power plant participation, disperse connection and nearby consumption, and some ways for improving consumption was explored.
