Low Carbon Economic Dispatching for Power System Integrated with Large Scale Photovoltaic Power Generation

Developing low carbon electricity is the key measure to cope with the challenge of global warming and to promote the sustainable development of the economy and society. As a clean energy that has developed rapidly in recent years, photovoltaic power generation has promoted the development of low carbon electricity. In this paper, a dispatching objective considering carbon emission based on carbon trading mechanism is established, so that the carbon emission has become schedulable resource owned economic value. As the photovoltaic power generation has the characteristics of randomness and volatility, the compensation cost of spinning reserve is introduced to the economic dispatching objective to cope with the impact caused by the photovoltaic power forecast error. On this basis, a new model of low carbon economic dispatching for power system integrated with large scale photovoltaic power generation is proposed. The model has been able to make the system operate economically and will effectively reduce carbon emission. Test results demonstrate the reasonableness and validity of the proposed model.
