Abstract

The invention discloses a shared energy storage control method and system for distributed renewable energy producers and disasters, and belongs to the field of energy consumption. The method comprisesthe following steps: minimization of the total energy cost of all prosumers, energy storage parties and operators participating in shared energy storage is taken as an objective function, wherein theenergy transaction cost in the power market takes downlink and uplink energy of an interface between an operator and a power system as decision-making quantity; the dispatchable load of the prosumergenerates benefits through power utilization, and actually control flexible load energy consumption in each prosumer control time period and energy consumption indirectly put forward to the energy storage party through an operator can serve as decision-making quantities; the energy storage loss cost of the energy storage parties takes the charging and discharging speed of each energy storage partyin the control time period and energy consumption proposed by a prosumer and indirectly received by an operator as decision variables, and constraint conditions are constructed for each decision variable to construct an energy system shared energy storage optimization control model; and the shared energy storage optimization control model of the energy system is solved by adopting distributed optimization to obtain a control scheme for multi-energy storage sharing by the prosumer.

Description

technical field [0001] The invention belongs to the field of renewable energy consumption in power systems, and more specifically relates to a shared energy storage control method and system for distributed renewable energy producers and consumers. Background technique [0002] Due to the increasing tension of traditional fossil energy, renewable energy has begun to receive widespread attention and development. In addition to large-scale renewable energy access to the grid, various small-scale decentralized renewable energy producers and consumers, such as installing rooftop photovoltaic systems for renewable energy Energy producers and consumers have also begun to develop rapidly. Renewable energy has the characteristics of intermittent and randomness, which poses a challenge to the dispatching work of the power grid; the grid connection of renewable energy has a great impact on the voltage and frequency of the large power grid, seriously affecting the power quality of the ...
