Model prediction/droop control based photovoltaic energy storage charging and discharging model 

A photovoltaic energy storage charging and discharging model based on model predictive control and droop control
1. Energy storage battery control:
(1) The voltage outer loop is for droop control, and the inner loop is for current model prediction
(2) Objective function: Constrain the difference between the predicted current and the given current
(3) The rated voltage of the battery is 180V, which can achieve charging and discharging
2. Photovoltaic+boost control:
(1) Incremental conductivity method 40 Ω
(2) The power is around 14.5kw
3. Bus and load conditions:
The rated voltage of the busbar is 400V, and the load is set to switch from 20 Ω to 8 Ω (the load power is adjusted from 8kw to 20kw)
4. Functionally, it can achieve maximum photovoltaic power output, prioritize meeting load power requirements, and surplus or insufficient energy
Coordinated by energy storage, the bus voltage changes with the battery current after droop control, ultimately achieving stability
