Abstract
In response to the global energy crisis, the integrated energy system has become an important part of the energy revolution. Aiming at the economic operation of the Integrated Energy System (IES), this paper proposes a system optimization planning model that takes the economic and environmental optimization as the goal and establishes a coupled capacity planning system, and jointly optimizes the capacity configuration and configuration of a single energy supply module. Power output to pursue maximum benefit. In order to illustrate the advantages of this method, on the basis of simulation, a dynamic programming method is used to solve the model. Finally, the simulation results show the effectiveness of the planning optimization model proposed in this paper, and provide a new path for solving the optimization problem of integrated energy system planning.
Highlights
With the advancement of industrialization and social and economic development, the world is facing severe energy crisis and environmental problems
In order to solve the increasingly severe energy and environmental dilemma, an integrated energy system came into being [1]
In the formula, y is the expected service life of the system, and r is the discount rate; ci is the cost of purchasing a single unit of different types of equipment; xi is the optimal number of different types of equipment in the planning optimization results; ji is the occupancy of each equipment in the integrated energy system The cost of land use; t i is the installation cost of a single unit of different types of equipment; el is the remaining cost in the construction phase
Summary
With the advancement of industrialization and social and economic development, the world is facing severe energy crisis and environmental problems. Research on the planning and optimization of the integrated energy system, by making full use of the complementary and alternative characteristics of different forms of energy such as electricity, gas, cold/heat in the system, and coordinated planning for the supply system of different forms of energy throughout the life cycle. It can suppress the uncertainty of renewable energy output in the system, realize the cascade utilization of energy, effectively improve the comprehensive utilization efficiency of energy, and promote the development and utilization of renewable energy [3]. In the Ref [6], the comprehensive energy system was planned under the quota condition, and the three benefits of economy, environment and society were realized
