Project Description

1) I need a complete design like the image that I attached.

2) There are 9 blocks. They are grid block, load block, inverter block, battery block, solar block wind block, fuel cell block, measurement block, control block. (Rectifier block may be added later)…..

3)I will give you all the blocks which would be designed already….you need to adjust the power rating according my requirement and make the network stable..

4) Control system should be work like the following way….

 Measure the value from the load

 Measure the value from all types of generations

 Calculate the power flow

 Collect resulting current and voltage from load flow calculation

 Supply the power generation according to the load demand. The power supply will depend according to the generation priority. The following generation will get the maximum priority (upper one will get 1st priority) for power supply.

1) Wind Power

2) Solar Cell

3) Fuel cell

4) Battery

5) Grid

 When the generation is more than the demand load then calculate the surpassed production

 Calculate the amount of surpassed production

 Calculate the maximum discharge from the battery

 Derive power flow to the Battery unit and calculate it

 When the storage unit will be full charged then power flow supply to the battery unit will turned off.

 Then the surpassed power will supply to the Grid

During the control design, following points must be consider

o Control P and Q set points for the energy hub (inverter/rectifier system)

o P > 0 the inverter feeds P into the network

o P < 0 the rectifier charges the battery

o And similar for Q

• Depending on the demand (or set point in the energy hub)

o Build small PID – type controllers (or just monitors in the case of wind and PV)

 Each controller will have:

• P setpoint (e.g. P_setpoint_battery) – only to curtail for wind and PV

• P measured (e.g. P_measured_battery)

o Depending on the setpoints for the energy hub you will need to adjust the setpoints of the subsystems (like battery, fuel cell, wind and PV) connected to the DC bus.

o Increase simulation to 24h scale

o Simulation matches the time step of the data series.

Here is the power rating......

Energy hub 100kW (with adjustable P/Q) (Inverter/Converter)

Wind power 30kW

Solar 30kW

Battery max power output 75 kW (buck converter or charge


Battery max charge 60kW (buck converter or charge pump)

Dump load 100kW

Fuel cell 3kW

Electrolyzer 4kW

Load is 500 KW

Grid......500 KW
