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

Developing low carbon electricity is a powerful measure to deal with global climate problems, which is also the internal motive force to promote the sustainable development of economy and society. As a clean energy, photovoltaic power generation has developed rapidly in recent years, which has a great impact on the energy saving and emission reduction of power system. In this paper, an economic dispatch model considering CO2 emission is proposed, 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 spinning reserve compensation cost is introduced to the objective function in order to deal with the prediction deviation of photovoltaic power generation. On this basis, a low carbon scheduling model integrated with 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.
