Regional Energy Optimal Allocation Method For Active Power Distribution Network Based On Integrated Re-source Strategy Planning

When facing the worldwide energy and environmental issues,the non-sustainability of traditional power planning method which only depends on increasing the power station investment in order to meet the rapid growth of electricity demand has emerged onto the surface.This paper carries on the research on regional energy expansion optimization of active distribution networks,which is based on the integrated resource strategic planning(IRSP),considering the photovoltaic power generation(PV)and interruptible load(IL)as the generalized power source from the perspective of the whole society.The main work are summarized as follows:(1)The power market,supply and demand balance is studied,the research status of active distribution network planning is surveyed and the IRSP theory is used to guide the planning considering the distribution generation and demand-side response technology.(2)The model of regional energy expansion optimization of active distribution networks is established,the upper level programming model optimized the power installation capacity of the generalized power sources by minimizing the total cost of power supply construction and maintenance,power generation and the governance of pollutants.The lower level programming model,which took the minimum network loss as the purpose,located and sized the generalized power sources.(3)Finally,comparing with the traditional planning,the performance and accuracy of the program are greatly improved,and the proposed model and the solution method has an obvious effect of social benefit in energy-saving,emission-reduction and resource utilization rate improvement,which was verified by the simulation analysis of IEEE 33 bus system.
