"Many to many"photovoltaic storage small group sharing energy storage configuration strategy
To improve energy storage utilization and on-site consumption of renewable energy,and reduce user electricity costs,a"many to many"photovoltaic storage small group shared energy storage configuration strategy is proposed.Each user in the small group is a photovoltaic producer and consumer,and multiple photovoltaic producers and consumers jointly invest in multiple shared energy storage.Taking the variable operation and maintenance costs of shared energy storage and the sum of small group purchasing and selling electricity costs,minus the minimum total benefit of reducing demand electricity bills,as the objective function,under the constraints of total installed power of energy storage and other energy storage operation conditions,the Gurobi solver is used to solve for the optimal number of storage units,power and capacity,as well as the optimal scheduling.Case analysis shows that under different allocation and storage ratios,the total cost of annual differences and annual purchase and sales of electricity in the small group shared energy storage model can be effectively reduced.Finally,conduct a sensitivity analysis on the variable operation and maintenance costs and basic electricity prices per unit of charging and discharging power.
