The invention discloses a method for constructing a load model that can be shifted in consideration of environmental costs and real-time electricity prices. The output of renewable energy is converted into economized environmental costs, and then combined with the existing real-time electricity prices to obtain a new electricity price model. Improve the target load model, and then build a new translational load model; at the same time, the linear interactive general optimizer, that is, the LINGO solver, is used to solve the translational load model, which can quickly and efficiently process large-scale linearly constrained integer quadratic programming The model is better than the traditional effective set method, interior point method, particle swarm optimization algorithm and other optimal solution algorithms in terms of solution speed and efficiency. This model is incorporated into the multi-objective optimal scheduling of the microgrid, which can more effectively reduce the power supply pressure of the grid during peak load hours, reduce the peak power used by electrical equipment, improve the utilization rate of renewable energy, and ultimately improve the reliability and economy of the entire system operation. sex.
Description
technical field [0001] The present invention relates to the related technical field of a shiftable load model, in particular to a method for constructing a shiftable load model considering environmental costs and real-time electricity prices. Background technique [0002] Due to the dual pressure of environmental protection and energy depletion, we are forced to vigorously develop clean and renewable energy. The development potential and benefit space of efficient distributed energy systems are huge. The microgrid can fully promote the large-scale access of distributed power and renewable energy, and realize the highly reliable supply of various energy forms for the load. It is an effective way to realize the active distribution network and make the transition from the traditional grid to the smart grid. . In order to achieve the goal of safety, reliability, economy, cleanliness, efficiency and interaction of the microgrid, it is necessary to conduct research on the optima...
