| The rapid development of the national economy has gradually improved the quality of people's lives,but it has also caused serious energy depletion and environmental pollution crises.On the one hand,the non-renewability of primary energy requires the development of new energy sources and improved energy efficiency,while the traditional energy system's independent management of various types of energy has limited the improvement of efficiency.On the other hand,the introduction of demand-side response in the planning stage can effectively improve the capacity of renewable energy consumption,while achieving the effect of delaying investment and improving planning economy.In this context,it is of great significance to carry out joint planning research of electric power and natural gas distribution networks that take into account the comprehensive demand side response.Based on the traditional distribution network planning,this paper considers the coordinated planning with the natural gas distribution network,and introduces a comprehensive demand response considering user satisfaction during the planning stage.Based on the modelling of comprehensive demand response and its compensation cost,this paper studies the combined planning model and method of electric-gas distribution network considering comprehensive demand response.The flexibility factor is introduced into power flow constraints.This paper explores the superiority of joint planning over traditional planning,and the impact of comprehensive demand response and flexibility coefficient on joint planning of electric-gas distribution network,and finally design an auxiliary platform for joint planning of electric-gas distribution network for practical work. |
