Abstract
The invention relates to a Cuckoo algorithm-based optical storage power station collaborative optimizaton method and device. The method comprises the following steps: S1, obtaining first data; s2, based on the first data, respectively obtaining a distributed photovoltaic model and an energy storage system model; s3, acquiring a coordinated optimization model of the optical storage power station; s4, obtaining constraint conditions, including obtaining an energy storage system constraint condition based on the energy storage system model, and obtaining a power market transaction electric quantity constraint condition and a distributed photovoltaic model optical storage power station power balance constraint condition; and S5, solving the optical storage power station coordinated optimization model to enable the optical storage power station coordinated optimization model to meet constraint conditions. The invention comprises respectively obtaining a distributed photovoltaic model and an energy storage system model based on first data; then obtaining a coordinated optimization model of the optical storage power station; and solving the optical storage power station coordinated optimization model by adopting a cuckoo algorithm, so that the solved optical storage power station coordinated optimization model meets constraint conditions, thereby realizing low operation cost.
Description
technical field [0001] The present invention relates to the technical field of power system dispatching, in particular to a method for collaborative optimization of optical storage power stations based on the cuckoo algorithm. Background technique [0002] On the one hand, large-scale renewable energy access to the power grid can effectively alleviate my country's huge demand for energy and the country's power shortage situation; Valley difference, affecting the stability of the system and so on. Solar energy is a resource-rich clean energy, and large-scale photovoltaic grid-connection has become a major trend. However, the natural random volatility and low controllability of photovoltaics make many types of decision-making problems such as power system planning and dispatching face higher uncertainty, which significantly increases the difficulty of decision-making. The challenges brought by large-scale photovoltaic grid-connection to power system dispatch mainly lie in how...
