simscape electrical 完成一天级的仿真

我需要使用simulink中的simscape electrical完成一天级的能量管理方案设计，这从理论上是否可行？

如果不可行的话应该用哪种方法？

如果我的调度精度为15分钟，是不是可以将仿真时间改为24*60/15=96？

Hi @ 智坤,

以下回复为英文,

I understand that you want to design a day level energy management using Simscape Electrical,

Using Simscape Electrical in Simulink for designing a day-level energy management scheme is theoretically feasible but the specific implementation and model construction will depend on your system requirements and complexity.

For a day-level energy management scheme, you would need to consider factors such as daily energy variations, energy storage, and energy consumption. You can build a model in Simulink that includes different power components and use Simscape Electrical libraries to model their behaviours. You can then simulate a day's worth of time using Simulink's simulation capabilities and observe the system's performance under different conditions.

Regarding simulation time, If your scheduling precision is 15 minutes, you can set the simulation time to 24 hours * 60 minutes/15 minutes = 96-time steps. This ensures that the simulation runs with a time step of 15 minutes throughout the day, capturing the dynamic behaviour of the system at different times.

Here are some general steps to guide you through the process of designing a day-level energy management plan using Simscape Electrical in Simulink:

• Utilize Simscape Electrical blocks to model electrical system components like generators, loads, batteries, and relevant devices.
• Develop control algorithms to manage energy flow, optimizing power generation, storage, and consumption based on factors like time of day and electricity prices.
• Set simulation time for the desired duration (e.g., 24 hours) and choose an appropriate time step for accuracy in your application.
• Execute simulations to analyse the energy management plan's performance over the specified time, utilizing Simulink tools for visualization and analysis.
• Refine control strategies and system parameters based on simulation results to optimize the overall energy management plan.

You can also refer to the below documentation on Simscape Electrical & Real time Simulation if required,
