【摘要】：微网是一种由多种分布式能源组成的新型网络结构,微网中社会福利最大化问题广泛地存在于微网优化中.为了降低微网中的发电成本同时让用户获得最大的受益,在考虑发电与用电限制,可再生能源的缺陷的同时,基于对数障碍罚函数,本文提出分布式一致性算法用于解决社会福利最大化问题,并且证明了算法的正确性和稳定性.飞轮储能系统的运用克服了可再生能源发电机自身的间歇性和不稳定性.仿真结果显示,在单一调节周期内,提出的算法能够在满足各种实际限制的情况下,很好地完成优目标.多调节周期内,在考虑可再生能源发电机发电量是时变的情况下,提出的算法也能在较短时间内求出稳定且正确的优化解.另一方面,优化的过程中产生的波动以及整个微网中的小幅度供需不平衡并不会对微网的稳定性造成大的影响.
[Abstract]:Microgrid is a new network structure composed of a variety of distributed energy sources. The problem of social welfare maximization in microgrid is widely used in microgrid optimization. In order to reduce the cost of power generation in microgrid and maximize the benefit of users, considering the limitation of power generation and electricity, the limitation of renewable energy, and based on logarithmic barrier penalty function, In this paper, a distributed consistency algorithm is proposed to solve the social welfare maximization problem, and the correctness and stability of the algorithm are proved. The application of flywheel energy storage system overcomes the intermittent and instability of renewable energy generator itself. The simulation results show that the proposed algorithm can achieve the optimal goal well under the condition of satisfying the practical limitations in a single regulation period. Considering that the generation of renewable energy generator is time-varying, the proposed algorithm can also obtain a stable and correct optimal solution in a short period of time. On the other hand, the fluctuation in the optimization process and the small supply and demand imbalance in the whole microgrid will not have a great impact on the stability of the microgrid.
