This paper takes the nodal voltage fluctuation and comprehensive multi-cost of ESS as the composite optimization objective, and combines multiple constraints to establish an energy storage configuration optimization model of the wind-solar-energy storage hybrid distribution network. Based on the optimization model, an improved multi-objective particle swarm optimizer (IMOPSO) is introduced to solve the problem. IMOPSO avoids the particle swarm from falling into the local optimal solution while considering the convergence speed and accuracy. Finally, through analysis of the IEEE-33 node distribution network system, the rationality of the proposed ESS configuration optimization model and the IMOPSO are verified, which can effectively reduce the nodal voltage fluctuation and power loss of the distribution network, and improve the system economy at the same time.","PeriodicalId":412421,"journal":{"name":"2022 4th International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123821195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, the flexibility retrofits of thermal power units that directly support local voltage source converter (VSC) stations are considered to enhance the grid integration of wind power and the operating economics of the HVDC system. The flexibility retrofit measures for thermal power include the application of high-power plasma ignition burners and the single-mill operation. The designed multi-terminal HVDC network is weakly connected with the sending-end high voltage alternating current (HVAC) grid. A hierarchical scheduling structure is presented to decompose the scheduling problem of the hybrid AC/DC system into three interactive levels, which can be solved by utilizing the analytical target cascading (ATC) method. Simulation studies indicate that the flexible operation of thermal power has been greatly improved so that the wind power supporting VSC stations can be better accommodated.","PeriodicalId":412421,"journal":{"name":"2022 4th International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114086684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to improve the prediction accuracy of renewable energies, a multi-application scenario coordinated control strategy for battery energy storage system (BESS) is proposed. Firstly, according to response requirements of BESS under different application scenarios, the power control strategies of BESS under peak load shifting scenario and prediction error compensation scenario are proposed respectively. Then, considering the priority of different application scenarios, the multi-application scenario operating area division method for BESS is proposed. Finally, a real-time secondary power regulation method of BESS is proposed based on the state of charge (SOC), and the multi-application scenario coordinated control strategy for BESS is proposed accordingly. The simulation case studies validate that the proposed strategy can effectively improve the BESS utilization rate, RE consumption ability, and prediction accuracy under various application scenarios.","PeriodicalId":412421,"journal":{"name":"2022 4th International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114338516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the process of using, the aged batteries reduce the battery endurance and cause an explosion. Therefore, it is necessary to estimate the state-of-health (SOH) and achieve battery equalization. This paper proposes a method for SOH estimations and balancing strategy based on balancing voltages and balancing current expectations. The real-time voltage differences are employed to get the balancing current expectations. In addition, the RMS of current can reach the current expectation by controlling the phase angle of hardware circuit, to realize the rapid convergence of battery voltage. With the ratio of cell-to-cell balancing current expectation, the SOH estimations of all cells within a series-connected battery pack can be obtained. Results show the SOH estimations relative error can be well controlled within 2%, and it takes less estimated time.","PeriodicalId":412421,"journal":{"name":"2022 4th International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121626554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experiments are performed to show that the proposed method could reduce the estimation error by 80.9%, 41.3% and 25.6% for LCO, LFP and NCA respectively. Moreover, to reduce the computation burden between different kinds of batteries, a transfer learning (TL) strategy is utilized by fine-tuning the dense layers.

It has been suggested that Sliding Mode Control (SMC) be used in the speed loop rather than PI control. This would eliminate the overshoot of the speed, make the speed fluctuation small when the load is suddenly applied, and allow the speed to be quickly restored to stability, all of which would improve the system’s ability to withstand shocks. Because the conventional vector control system for permanent magnet synchronous motors needs to execute three coordinate changes, an improved proportional resonance (PR) controller is utilized in the current loop. This particular controller does not include compensation items related to motor parameters. the complex nature of the computation.
