Integrated Energy Storage And Energy Sharing Optimization Strategy For Park Level Power System

According to China’s carbon dioxide emissions.Breaking down the barriers between energy sources,promoting multi-energy complementarity and improving overall energy utilization efficiency is an imperative step in energy transformation.Focusing on improving the consumption and storage capacity of new energy,the traditional power grid will transform into a new type of power system that achieves carbon peak and carbon neutrality,providing strong support for building a clean,low-carbon,safe and efficient energy system.Comprehensive energy systems have gradually become an important part of the energy field in this context.This study aims to address the problems of long-distance transmission in traditional power grids,single types of energy sources,and high grid burden during peak and offpeak electricity usage by constructing a comprehensive energy system for efficient coupling and utilization of energy within a region.It couples and relates different forms of energy,such as electricity,heat,and gas,improving the energy supply structure from the supply and transmission side.At the same time,it integrates energy storage equipment and user-side adjustable resources,improving the flexibility of demand-side participation in energy system regulation.With the new situation of energy transformation,some management methods on the demand side also need to be simultaneously optimized and upgraded.Demand response and energy sharing have become important regulation methods due to their efficient resource regulation capabilities and universal applicability.With the promotion of comprehensive energy parks nationwide,more and more comprehensive energy microgrids are located close to each other in terms of geographical location and depend on each other in terms of energy relationships,meeting the basic conditions of multi-network governance.At the same time,with the development of energy storage strategies,this paper sets up a shared hybrid energy storage station for participation to pursue the lowest total operating cost of the multi-network system.Therefore,this study investigates the model construction and strategy formulation of single-network optimization and multi-network optimization of the comprehensive energy system in the park.The new energy access and diverse user energy demands proposed by the new power system pose higher requirements for comprehensive energy planning theory.To address this issue,this study develops a combined heat and power storage system that coordinates with the comprehensive energy system,proposing a collaborative planning optimization model with the goal of minimizing economic costs while considering reliability.Meanwhile,an energy trading and sharing strategy is proposed for multi-microgrid governance scenarios,with constraints such as supply-demand balance,network transmission,energy storage lifecycle,and device output limitations,and the multi-objective optimization algorithm is chosen to solve the optimization model.
