用户侧互动模式下的微电网优化协调调度策略研究

随着可再生能源的不断渗透,微电网的管理呈现出复杂性与多样性,制定高效的调度策略不仅能够减轻大电网的负担,更能实现彼此互利共赢。文章针对同时具有风光柴储的典型微电网,研究在并入外部电网的情况下,最大化地发挥用户侧与微电网的互动潜力,协调各微电源之间出力得到优化调度策略。最后,依据所提出的评价指标对每一种优化调度策略进行评估。通过仿真与对评价指标的计算,验证了所提出调度策略的有效性与合理性。

Research on Optimal Coordination Scheduling Strategy of Micro - grid in User - side Interactive Mode

With the continuous penetration of renewable energy, the management of micro-grid shows complexity and diversity. The development of efficient scheduling strategy can not only reduce the burden of the large grid, but also achieve mutual benefit and win-win situation.This paper focuses on such a micro-grid with a wind generator,a photovoltaic system, a diesel generator and an energy storing device.In the case of incorporating the external power grid, the interactive potential between the user side and the micro-grid is maximized, and the optimal scheduling strategy is coordinated between the outputs of each micro power source.Finally, according to the proposed evaluation indexes, each optimal scheduling strategy is evaluated.The effectiveness and rationality of the proposed scheduling strategy are verified by simulation and calculation of evaluation indexes.
