The investigation of the optimization based on market mechanism to the operation of a thermal‐wind‐photovoltaic hybrid generation system.

The renewable energy hybrid generation system in the area with renewable energy and land source plays a key role in improving the application of the renewable energy in China, with the rapid development of the extra high voltage (EHV) and ultra‐high voltage (UHV) grids to transmit the electricity. The suitable plan and decision‐making mechanism has a significant influence on the utilization of the renewable energy. The output of thermal power, wind power and photovoltaic are respectively simulated in the plan period of a hybrid generation system, and then all the output are comprehensively studied with the consideration of some constrains. However, the experience of the applications of the renewable energy hybrid generation system with thermal power revealed an obvious disadvantage that to maintain the competitiveness of the power output without the guidance of the price signals in the electricity market is difficult. The dispersed areal distribution and discontinuous power output of the renewable energy may be responsible for this disadvantage. The investigation to improve the consumption of the renewable energy hybrid generation system is meaningful to solve the renewable energy curtailment problems. In the present study, the investigation to the operation of a thermal‐wind‐photovoltaic hybrid generation system with market mechanism was conducted to optimize the consumption of the renewable energy. These results are beneficial to the operations of the similar hybrid generation systems. [ABSTRACT FROM AUTHOR]
