    摘要:

    传统微电网存在用户间缺乏互动性、可再生能源利用率低等问题。本文考虑不同气候条件下光伏出力及智能楼宇内储能的运行模式,提出基于多主体互动的微电网运行模式,用于优化微电网的用户用能成本,同时提升可再生能源的消纳能力。首先,对比分析微电网经典运行模式及多主体互动运行模式,研究各主体在不同模式下的用能行为;然后,灵活制定合约电价,提升智能楼宇运营商与电动汽车充电站运营商在微电网内电能互动的效率,并进一步分析多主体互动模式下微电网内部的能量流动情况;最后,考虑环境因素对光伏出力的影响,分析不同运行模式下微电网内用户的用能成本以及微电网消纳可再生能源的能力。仿真结果表明,在采用多主体互动模式时,在光照条件充足时,可再生能源消纳率从经典运行模式的67.83%提高到了100%,同时减少了智能楼宇运营商及充电站运行商的用能成本。

    Abstract:

    Traditional microgrids have problems such as lack of interaction among users and low utilization rate of renewable energy. Considering the operation mode of photovoltaic (PV) output and energy storage (ES) in smart buildings under different climatic conditions, this paper proposes a micro?grid operation mode based on multi?agent interaction to optimize the user's energy cost of the micro?grid and improve the ability to absorb renewable energy simultaneously. First, this paper compares and analyzes the classic operation mode of microgrid and the multi?agent interactive operation mode, and studies the energy consumption behavior of each agent in different modes; Then, the contract price is set flexibly to improve the efficiency of the energy interaction between the smart building operators and the electric vehicle (EV) charging station (CS) operators in the microgrid, and the energy flow inside the microgrid under the multi?agant interaction mode is analyzed; Finally, considering the impact of environments on PV output, the energy cost of users in the microgrid under different operating modes and the microgrid’s capacity of renewable energy consumption are analyzed. The simulation results show that the multi?agent interaction mode of the microgrid increases the consumption rate of renewable energy from 67.83% of the classic operation mode to 100% when the light conditions are sufficient, and at the same time optimizes the energy cost of smart building operators and CS operators.
