用python实时模拟电池充电

Question

我试着用simpy模拟电池充电。所需参数是电池容量(W)、电池充电状态(百分比)和充电器充电功率(W/h)。

我的代码如下所示：

import simpy
import random

battery_percentage = []

class ChargingCycle(object):
    def __init__(self, env, battery_capacity, SoC, charging_power):
        self.env = env
        self.battery_capacity = battery_capacity
        self.SoC = SoC
        self.charging_power = simpy.Resource(env,charging_power)

    def charge(self, battery):
        print(self.charging_power)
        power_per_minute = self.charging_power/60
        charge_in_kw = (self.SoC/100)/self.battery_capacity
        charge_in_kw += power_per_minute
        self.SoC = charge_in_kw/self.battery_capacity*100

    
def start_charging(env, battery, charging):
    with charging.charging_power.request() as request:
        yield request
        yield env.process(charging.charge(battery))
    

def run_charging(env, battery_capacity, SoC, charging_power):
    charging = ChargingCycle(env, battery_capacity, SoC, charging_power)
    battery = 0
    while True:
        yield env.timeout(1)
        battery += 1
        env.process(start_charging(env, battery, charging))

def main():
    env = simpy.Environment()
    env.process(run_charging(env,45000, 10, 7630))
    env.run(until=360)

if __name__ == "__main__":
    main()

基本上，我希望每分钟都能获得充电功率，每分钟我都会将充电器给电池的能量添加到可变的charge_in_kw中，并更新充电SoC的状态。

当我运行模拟时，会得到以下错误：

File "c:\Users\sc57978\Desktop\OCPP\sim_charge.py", line 17, in charge
power_per_minute = self.charging_power/60

TypeError: unsupported operand type(s) for /: 'Resource' and 'int'

有人知道我怎么解决这个问题吗？

Answer 1

在运行并执行了大量调试之后，我能够运行您的代码，我做了以下更改以使其运行

• 从charging_capacity资源中获取值以解决实际错误
• 添加yield self.env.timeout(1)以解决进一步的负责函数

错误

最终运行代码

class ChargingCycle(object):
    def __init__(self, env, battery_capacity, SoC, charging_power):
        self.env = env
        self.battery_capacity = battery_capacity
        self.SoC = SoC
        self.charging_power = simpy.Resource(env, charging_power)

    def charge(self, battery):
        print(self.charging_power)
        power_per_minute = self.charging_power.capacity/60
        charge_in_kw = (self.SoC/100)/self.battery_capacity
        charge_in_kw += power_per_minute
        self.SoC = charge_in_kw/self.battery_capacity*100
        yield self.env.timeout(1)


def start_charging(env, battery, charging):
    with charging.charging_power.request() as request:
        yield request
        yield env.process(charging.charge(battery))

    charging = ChargingCycle(env, battery_capacity, SoC, charging_power)
    battery = 0
    while True:
        yield env.timeout(1)
        battery += 1
        env.process(start_charging(env, battery, charging))
