Embodiment 1
[0046] figure 1 It is a schematic diagram of a test method for a microgrid energy management system according to Embodiment 1 of the present invention, as shown in figure 1 As shown, the testing method for the microgrid energy management system of this embodiment includes the following steps:
[0047] Step S1: Build a microgrid model on the RT-LAB real-time simulation host; the microgrid model includes at least one model of a renewable energy power supply device, at least one model of an energy storage device, and a communication interface for a microgrid, wherein the model of a renewable energy power supply device and The energy storage device models are respectively connected to the microgrid communication interface; for example, the renewable energy power supply device models are green energy power supply devices such as fan models and photovoltaic models; the energy storage device models include energy storage converters (Power Control System—PCS) and The energy storage s...
Embodiment 2
[0053] see Figure 4 As shown, it is a wind-solar storage and off-grid microgrid system, in which the renewable energy power supply device includes a photovoltaic device 1, a photovoltaic device 2 and a fan device, as well as an energy storage device and a load device integrated into the grid.
[0054] In this embodiment, the above-mentioned microgrid model is built on the RT_LAB real-time simulation host, this step is similar to step 1 in Embodiment 1, and will not be repeated here. And, each device model in the microgrid model is connected to the inverter model, such as Figure 4 It includes photovoltaic inverter 1, photovoltaic inverter 2, wind turbine inverter and energy storage inverter. These inverters can collect the microgrid status information in real time, and perform Processing and calculation of real-time power, taking photovoltaic inverter 1 as an example, it can collect the state information of its corresponding photovoltaic device 1, including real-time collect...
