Regional interconnected comprehensive energy multi-objective optimization configuration method

Abstract

The invention discloses a regional interconnected comprehensive energy multi-objective optimization configuration method. According to the method, a three-region interconnected electric power system containing a comprehensive energy system is built, a region A includes the comprehensive energy system, regions B and C represent two conventional regional networks, and the three regions are interconnected through connecting lines; the region A finally transmits energy generated by the system to terminal users reasonably and efficiently through respective inferior energy transmission networks by means of equipment elements of an energy coupling part, energy requirements of the terminal users for cooling, heating and power loads are met, and the region A comprehensive energy system based on anenergy concentrator is established; energy interaction between the system and an energy bus including a power grid and a heat supply network is considered, and comprehensive energy system energy interaction structure containing a multi-energy network for the regional A power grid is established; and targets related to a planning capacity variable and a system operation variable are considered, anda regional interconnection comprehensive energy multi-target optimal configuration mathematical model considering regional control deviation is constructed.

Description

technical field [0001] The invention relates to the technical field of comprehensive energy systems, in particular to a multi-objective optimal configuration method for regional interconnected comprehensive energy. Background technique [0002] With the acceleration of fossil fuel consumption, environmental pollution is becoming more and more serious. In the traditional energy system, the design, planning, operation and control of energy subsystems such as electricity, heat, and cooling are often independent of each other, and the overall energy utilization rate is low, while the integrated energy system (Integrated Energy System, IES) can coordinate various energy sources. Optimization, to achieve efficient use of renewable energy, to meet the various energy needs of users, so more and more countries have shifted their research focus from traditional energy to comprehensive energy. [0003] Economic development needs energy as a driving force. At present, renewable energy ...

Problems solved by technology

[0005] Considering the widespread use of integrated energy systems today, if the area of ​​the integrated energy system is interconnected with other areas, if a load disturbance occurs at a certain moment in the system, the economy, environmental protection, reliability, and interactive power fluctuations should be taken into account. The power and frequency of the tie line exchange in the entire interconnected system is more complicated to realize the optimal allocation of energy in the large-scale interconnected power system grid.
