In this paper, the techno-economic feasibility and flexibility of hybrid renewable energy systems are demonstrated under both off-grid and on-grid modes for rural electrification, where a case study of a village in West China is presented.
China''s renewable energy capacity, especially that of wind and solar, has witnessed rapid growth since the implementation of its Renewable Energy Law on 1 January 2006. By the end of 2016, the total installed capacity of wind and solar power in the country had reached 169 GW and 78 GW respectively, in both cases the largest of any country in the world.
To address the challenges associated with grid integration costs and land consolidation in the site selection of large-scale PV power plants, this study proposes an
With the continuous advancement and deepening of reform of the power system, however, China’s policies regulating the construction of microgrids have been continuously improving, which has strongly promoted the construction and development of microgrids. 2.4 Existing Mini- and Microgrid Projects in China

Determining the energy yield, specific yield and performance ratio of the grid connect PV system.
The future development direction of microgrids in China will therefore be towards an energy system that integrates electricity, gas, water, and heat resources, achieves mutual coupling, and solves the problems of efficient energy utilization and peak regulation .
In contrast, PV production of Chongqing's grid-connected PV system provides just 40.1% of the total electricity required because of more limited solar radiation. It is worth noting that the technical feasibility of grid-connected PV systems must depend on the services of grid operators.
As a result, traditional producers and PV power generation may move towards a fair competitive environment, which is more conducive to grid parity of PV power generation. In addition, China's carbon trading is fully implemented in 2017, covering eight sectors including power sector.
