Abstract EN
The large-scale electric vehicles connected to the microgrid have brought various challenges to the safe and economic operation of the microgrid.
In this paper, a hierarchical microgrid dispatching strategy considering the user-side demand is proposed.
According to the operation characteristics of each dispatch unit, the strategy divides the microgrid system into two levels: source-load level and source-grid-load level.
At the source-load level, priority should be given to the use of the renewable energy output.
On the basis of considering the user demand, energy storage, electric vehicles, and dispatchable loads should be utilized to maximize the consumption of the renewable energy and minimize the user’s electricity cost.
The source-grid-load level can smooth the tie-line power fluctuation through dispatching of the power grid and diesel generators.
Furthermore, the study presents a modified MOEA/D algorithm to solve the hierarchical scheduling problem.
In the proposed algorithm, a modified Tchebycheff decomposition method is introduced to obtain uniformly distributed solutions.
In addition, initialization and replacement strategies are introduced to enhance the convergence and diversity.
A wind-photovoltaic-diesel-storage hybrid power system is considered to verify the performance of the proposed dispatching strategy and the modified algorithm.
The obtained results are compared with other dispatching approaches, and the comparisons confirm the effectiveness and scientificity of the proposed strategy and algorithm.
