Abstract

The invention discloses a multi-microgrid interconnected operation coordinated scheduling optimization method in consideration of interaction response. The method comprises the following steps: initializing a system and acquiring a related parameter in the day-ahead optimization process, wherein each microgrid independently solves the respective optimization strategy according to the initialization information; and then performing information interaction in a microgrid cluster to share the respectively acquired optimal strategies, and updating the system state information, wherein a system control center judges whether the Nash equilibrium is achieved; entering the intra-day optimization stage, performing short-term prediction on the scenery output and load demand, inputting the short-termprediction data in single microgrid to establish an optimization model, performing rolling optimization on the system and solving the same; selecting all control variables in a control time domain asthe actual scheduling scheme after the solution is finished, waiting for the next optimization period, and repeating the above optimization process. Through the optimization method disclosed by the invention, the consumption capacity on the new energy by the microgrid and the system reliability in the fault can be effectively improved, and the economic benefit of the microgrid is increased to a certain degree.

Description

technical field [0001] The invention belongs to the technical field of multi-microgrid interconnection operation optimization, and specifically relates to an optimization method for multi-microgrid interconnection operation coordination scheduling considering interactive response. Background technique [0002] In today's society, the extensive use of fossil fuels such as coal and oil has made global climate and environmental problems increasingly prominent. Facing increasingly severe energy and environmental problems, it is no longer a long-term solution to rely solely on fossil energy to supply human daily work. Therefore, we can The development of renewable energy has become the current mainstream direction in the energy field. However, due to the strong randomness, intermittency, volatility and uncontrollability of renewable energy, it is difficult to maximize the utilization of renewable energy. Only the efficient transmission of renewable energy power generation and the...
