摘 要:為了提高可再生能源的利用率,兼顧綜合能源系統(tǒng)的運行經濟性及風電、光伏消納等多個目標,建立了含電轉氣設備的電、氣、熱互聯的綜合能源系統(tǒng)調度模型。以綜合能源系統(tǒng)的運行成本、棄風和棄光量最小為目標,利用多目標模糊加權法將多目標問題轉換為單目標問題,并遍歷權值求解出帕累托解集,再根據熵值法的灰靶決策理論選擇兼顧運行經濟性和可再生能源利用率的調度計劃。通過算例仿真,得出含電轉氣的綜合能源系統(tǒng)可以有效促進可再生能源消納。
關鍵詞:綜合能源系統(tǒng);多目標調度;模糊加權;灰靶決策;電轉氣

Abstract: In order to improve the utilization rate of renewable energy, take into account the operation economy of the integrated energy system and the consumption of wind power and photovoltaic power, a comprehensive energy system dispatch model with electricity, gas, and heat interconnection including electricity-to-gas equipment has been established. With the goal of minimizing the operating cost, wind abandonment and light abandonment of the integrated energy system, the multi-objective problem is converted into a single-objective problem using the multi-objective fuzzy weighting method, and the Pareto solution set is solved by traversing the weights, and then based on the entropy method the gray target decision-making theory chooses a dispatch plan that takes into account both operating economy and renewable energy utilization. Through simulation, it is concluded that the integrated energy system containing electricity to gas can effectively promote the consumption of renewable energy.
Key words: integrated energy system; multi-objective scheduling; fuzzy weighting; gray target decision-making; electricity to gas
