The Model of Environmental Impact Assessment of Generation Dispatch Based on Environmental Value

At present, the government´s policy on discharging pollutants of power plant is a nationally unified pollution charge standard. Considering the shortcomings of existing Pollution Charge System (PCS), an environmental value model of pollutant based on the cost of prevention is proposed in this paper; Besides, an Environmental Impact Assessment (EIA) model of generation dispatch is presented in this paper; Finally, a calculation example is given to analyze the difference of two methods that measure Environmental Loss (EL), the results of analysis show that the comprehensively Environmental Value (EV) of pollutant is more precise in reflecting EL than purely Pollution Charge (PC); The calculation example also analyzes the environmental impact of Energy-saving Generation Dispatch (ESGD) in the different condition of environmental cost, the results of analysis not only provide a reasonable and reliable basis for implementing ESGD, but also verify the effectiveness and rationality of the model of EIA.
