热电联产储能matlab

### 热电联产储能系统的Matlab建模与仿真

#### 构建热电联产模块
在Matlab/Simulink环境中，热电联产（CHP）模块的设计基于燃料输入量和效率特性来计算电能和热能输出。具体来说，通过定义燃料消耗率以及相应的发电和供热效率曲线，可以精确模拟CHP设备的工作性能[^1]。

function [power, heat] = chpModel(fuelInput, efficiencyCurve)
    % CHP model function to calculate power and heat output based on fuel input.
    
    % Efficiency curve is a structure with fields 'electricEfficiency' and 'thermalEfficiency'
    electricOutput = fuelInput * efficiencyCurve.electricEfficiency;
    thermalOutput = fuelInput * efficiencyCurve.thermalEfficiency;

    power = electricOutput;  % Electric Power Output (kW)
    heat = thermalOutput;    % Thermal Heat Output (kJ/h)
end

#### 设计储能子系统
对于储能部分，电池SOC（State of Charge）计算模块和水蓄热罐蓄热状态计算模块被用来跟踪能量存储水平的变化。这些模块通常会集成积分器用于累积电量变化，并设置逻辑判断以决定何时充电/放电或储热/释热操作。

% Battery SOC Calculation Module Example Code Snippet
batteryCapacity = 200e3;     % Rated Capacity in Wh
initialSOC = 0.8;            % Initial State Of Charge as fraction between 0 and 1
    
function new_soc = updateBatterySOC(currentPowerFlow, dt, initialSoc)
    energyChange = currentPowerFlow * dt / 3600;      % Convert from Ws to kWh
    finalEnergyLevel = batteryCapacity * initialSoc + energyChange;
    new_soc = max(0,min(finalEnergyLevel/batteryCapacity, 1));  
end

#### 实现整体协调控制策略
为了使整个系统能够有效地协同工作，在各组件间建立必要的通信接口至关重要。这可以通过Simulink中的信号连线完成，从而允许实时交换有关生产、消费及储存的信息流。此外，还需要制定合理的调度算法来指导资源分配并最大化经济效益或环境效益等目标函数[^2]。

    dispatchStorageToSupplyDeficit();
elseif excessRenewableEnergyPresent()
    storeExcessInBatteriesOrThermalReservoirAsAppropriate();

    adjustCHPOperationBasedOnEconomicDispatchCriteria();
