HFCEV的加氫仍然是一個亟待解決的問題。本文提出一種基于氫電微網(wǎng)來生產(chǎn)氫氣，為HFCEV加氫，并提出了不同的策略來引導(dǎo)HFCEV在交通網(wǎng)絡(luò)與電力系統(tǒng)耦合下的加氫行為。首先，根據(jù)實際交通網(wǎng)絡(luò)構(gòu)建HFCEV交通流模型。其次，建立實時仿真算法。第三，構(gòu)建基于氫氣的微電網(wǎng)為HFCEV加氫。第四，建立IEEE 30節(jié)點電網(wǎng)輸出功率模型。最后，提出通過交通網(wǎng)絡(luò)與電力網(wǎng)絡(luò)的耦合實現(xiàn)HFCEV實時加氫。耦合結(jié)構(gòu)如圖1，并比較了不同的HFCEV加氫策略（固定價格、動態(tài)價格、LSTM決策價格）。結(jié)果表明，在動態(tài)價格下，交通網(wǎng)絡(luò)的擁堵得到改善，等待時間減少了17.71%，網(wǎng)絡(luò)的時間損失減少了13.29%。通過合理的價格引導(dǎo)，車輛會選擇指定的站點進行氫氣加注，并影響交通網(wǎng)絡(luò)車流量的時空分布。此外，通過調(diào)整發(fā)電站輸出功率和加氫站輸入功率，可以改善電力系統(tǒng)的電壓條件。
圖1 電網(wǎng)-微網(wǎng)-交通網(wǎng)耦合結(jié)構(gòu)
分析了四種不同的電網(wǎng)耦合交通網(wǎng)結(jié)構(gòu)如下圖2所示：
1) In Case 1, the power station is not considered, only microgrids are considered;
2) In Case 2, the power station is considered, the exporting power of the power station is adjusted based on the selling price, and the selling price is adjusted based on the utility grid voltage; in addition, in microgrid, the hydrogen price is adjusted based on the traffic congestion;
3) In Case 3, the power station is considered, the difference is that in the microgrid, the hydrogen price is adjusted based on the utility grid voltage and the traffic congestion;
4) In Case 4, an LSTM network is adopted to train the relationship between states (voltage, traffic flow) and the price. The hydrogen price is decided based on the smart LSTM network.
此外，在Case 1中3種不同的價格場景Case 1A, Case 1B, and Case 1C被進行比較，包括：
Case 1A：hydrogen price is not considered, and vehicles choose the nearest distance station to refuel hydrogen;
Case 1B：fixed hydrogen price is considered;
Case 1C：dynamic hydrogen price is considered, and the price is dynamically adjusted basedon the traffic congestion. Three different users choosing refuelling station strategies are compared.
