Solar photovoltaic webex: in photovoltaic power parity project technical scheme symposium on reliability and economy analysis, its energy research institute of new energy and statistics institute, sheng wang hui, 2019, if consider new energy ( Wind power + photovoltaic) The new size and flat in 2018, to implement a new energy abandoned electric rate fell below 5%, must carry on the optimization to the layout of new power: one is the strict control of xinjiang, gansu, hebei, jilin north abandoned electric areas such as new scale; Second, priority arrangement don't abandon electricity or less abandoned electric areas of installed, moderate increase in eastern new energy installed scale; Three is to optimize years new power sequence, in principle much arrangement in the fourth quarter grid.
