Embodiment Construction
[0040] The preferred embodiments of the present invention will be further described in detail below.
[0041] Such as figure 1 As shown, an independent microgrid energy management method considering random prediction error, which includes the following steps:
[0042] (1) The energy management system EMS predicts the load and the power of renewable energy (wind power, photovoltaic) in the future;
[0043] (2) Use CPLEX to optimize, specify the operation plan before the day, and the micro power source (micro gas turbine and energy storage battery) will operate according to the plan;
[0044] (3) The EMS monitors the SOC state of the energy storage battery in real time, measures the actual power generated by wind power and photovoltaics, and measures the actual power of the micro-turbine and the energy storage battery; according to the predicted and actual monitored power, the random prediction error of the net load is obtained, which is the actual running error;
[0045] (4)...
