Embodiment 1
[0107] An embodiment of the present invention provides a method for safe and economic dispatch of electric energy in a microgrid, the specific implementation process of which is as follows figure 1 shown, including:
[0108] S101: Bring the operation data of adjustable resources in the microgrid into the pre-established microgrid operation model, and obtain the adjustable The active output reference value of resources within the set time scale;
[0109] S102: Based on the active output reference value, the pre-collected renewable energy forecast data and load forecast data, perform power flow calculation on the microgrid to obtain the initial voltage value of each node, and according to the node voltage The initial value determines the node where the voltage exceeds the limit;
[0110] S103: For the node where the voltage exceeds the limit, correct the active output range of the adjustable resource through the preset voltage control strategy, and feed back the corrected acti...
Embodiment 2
[0149] In the embodiment of the present invention, the IEEE 33 node power distribution system is used to simulate the structure of the microgrid, as shown in Figure 5. Among them, two micro gas turbines are connected to nodes 2 and 8, with rated capacities of 80 kW and 55 kW respectively; one fuel cell is connected to node 24, with a rated capacity of 60 kW; wind turbines and photovoltaics are connected to nodes 27 , 30, with a rated capacity of 30kW; the access location of the energy storage is node 16, with a rated capacity of 200kWh; two electric vehicles are respectively connected to nodes 20 and 32, with a battery capacity of 32kWh and a rated charging power of 7kW. Below, the simulation results of the embodiment of the present invention are described:
[0150] Depend on Image 6 It can be seen that after using the method provided by the present invention for microgrid power scheduling, the voltage amplitude of the system nodes has been greatly improved, and the average ...
Embodiment 3
[0152] Based on the same inventive concept, the present invention also provides a microgrid electric energy safety and economic dispatch system, the system structure diagram is as follows Figure 7 As shown, the system includes:
[0153] The system includes:
[0154] The scheduling module is used to bring the adjustable resource operation data, renewable energy forecast data and load forecast data in the microgrid into the pre-established microgrid operation model, and obtain the adjustable resource in the microgrid in the set Active power output reference value in time scale;
[0155] The execution module performs power flow calculation on the microgrid based on the active output reference value, obtains the initial voltage value of each node, and checks whether each node has a voltage exceeding the limit;
[0156] The correction module, for the node where the voltage exceeds the limit, iteratively corrects the active output range of the adjustable resource through the set ...
