If this reserve capacity is not properly prepared, the power system may be in a dangerous state. In this paper, a day-ahead generation schedule of wind-thermal-storage system considering prediction error of wind power and load is proposed to ensure the security of this reserve capacity, as well as, which effectively coordinates the economy and safety of the day-ahead generation schedule. The actual value is regarded as the sum of the predicted value and its deviation for wind power and load in the proposed method. Among them, the predicted deviation is balanced and tracked by the automatic generation control (AGC) unit, and its output active power and reserved reserve capacity are modeled. What's more, the AGC has sufficient adjustable upper and lower limits to balance the electric power by applying constraints, and has the ability to track the fluctuation of the prediction deviation. Furthermore, since the prediction deviation is a random number, the model with random parameters is transformed into a deterministic model through a robust peer-to-peer model to verify the effect in the extreme scenario, as well as, a distributed energy storage device is introduced to promote wind power consumption and optimize the system operation economy. Finally, in an IEEE 30 node system, the background of high proportion of wind power connected to the power system is set, and the security and economy of reserve capacity under the extreme scenario are analyzed through the method proposed in this paper.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123612645","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 make full use of the battery energy storage system to delay the upgrading and reconstruction of the distribution network, a comprehensive optimization method of selecting the site and capacity to participate in the peak load regulation of distribution network is proposed. In the proposed method, a bilevel planning model is built where the upper layer model is the capacity configuration model, which considers the investment income of DESSs and delaying the expansion and upgrade of the distribution network; whereas the lower layer model is the installation spot optimization model, which considers the characteristics and capacity limit of DESSs, and the load regulation for peak-load shifting. The validity of the proposed method is verified by the IEEE 33-bus system. Simulative results show that, the proposed comprehensive optimization method is suitable for different application scenarios with the integration of DESSs of different capacity configurations and different installation spots and can provide a technical support for the planning and managing of largescale DESSs accessing to the distribution network.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125755639","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}

The simulation results show that with the increase of the auction proportion in the primary CET market, the electricity price in the electricity market keeps rising, and the discriminatory-price auction is more suitable for China's national conditions. The discriminatory-price auction can stimulate the enthusiasm of power generation firms to participate in carbon trading, and enable the government to obtain higher revenue.

However, most PFR performance evaluation depends on the unit performance test which leads to a result different from the actual operation performance. In this paper, a PFR performance evaluation based on frequency regulation data segment identification in daily operation is proposed. Firstly, the ramping data segments from daily operating data are selected by the improved swinging door algorithm. Secondly, PFR data segments are identified by three rules. Thirdly, three evaluation indicators including the response time, the adjustment coefficient, and the stable time of the units are calculated and a comprehensive index is formulated to evaluate the PFR performance of thermal power units by the entropy-osculating value method.

Green electricity and carbon market mechanism will help China achieve the “dual carbon.” Under the existing green electricity trading mechanism, the carbon reduction benefits of wind power are quantified and converted into an environmental premium. Considering the environmental premium and carbon cost, a low carbon economic scheduling model with wind power system is established. MATLAB and CPLEX are used to solve the problem, and the influence of different carbon prices on dispatching costs is analyzed. The results show that the above model can effectively take the impact of carbon quota and environmental premium of renewable energy on the power generation cost into consideration.

The urban distribution network has high requirements on power quality, and the use of flexible DC technology is the best choice at present. Different from traditional motors, the flexible DC system has low inertia and small damping. When the fault occurs on DC line, the current rising rate is extremely fast, which seriously threatens the safe operation of the urban distribution network. It is necessary to design high-reliability and fast protection according to its fault characteristics. This paper proposes a pilot protection method based on transient high-frequency impedance by analyzing the variation characteristics of transient electrical quantities after a DC line fault. And regional protection can also be formed through the cooperation of adjacent lines.
