In order to solve this problem, this paper first summarizes the inertia index of conventional units, and combs out the effective calculation method of inertia of conventional units. Secondly, this method is extended to the inertia estimation of the new energy power system to evaluate the inertia of the new energy power system. Then, considering the minimum safety inertia evaluation of new energy power system constrained by the rate of change of frequency, the minimum safety inertia coefficient of new energy is defined and taken as the evaluation index.

Focusing on DT, this paper firstly analyzes the development mode of DT system, including symbiosis, evolution and optimization, and puts forward key technology on fusion modeling, neural network optimization and intelligent decision making. Secondly, from the view of source, network, load and storage, this paper deeply summarizes and refines the current methods of the DT model building in IES.

The conclusion showed that the phase-selective closing and closing resistors installed in the circuit breaker can reduce the inrush current, but the effect of suppressing such overvoltage was very small.

In order to meet the demand for short-term peak load, two schemes are typically adopted: substation capacity expansion and co-construction of energy storage stations. However, both schemes have their advantages and disadvantages. In order to better select the scheme, it is necessary to establish a reasonable comprehensive evaluation index system. This paper proposes a scheme comparison method based on improved AHP (Analytical Hierarchy Process) – FCE (Fuzzy Comprehensive Evaluation). We construct the evaluation index system for substation capacity expansion and co-construction of energy storage stations. Then, the comprehensive evaluation scores under the two schemes are obtained using the AHP method to calculate the weight of each index, combined with fuzzy comprehensive evaluation.","PeriodicalId":425438,"journal":{"name":"2022 12th International Conference on Power and Energy Systems (ICPES)","volume":"94 8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127986489","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}

To implement frequency control on PV, additional energy storage or power deloading is required, which brings additional cost to the PV station. Official technical standards and grid codes in a few countries and regions have specified the requirements for PV frequency control. Following the typical standard of frequency droop control, it is necessary to utilize the remaining PV power reserve to improve frequency characteristics such as frequency nadir and rate of change of frequency (RoCoF), and frequency shaping (FS) control is a promising solution for this task. With parameter tuning based on system model, frequency shaping control is implemented together with a fixed droop required by the grid code. The control strategy is tested with simulation, which shows frequency response with nadir eliminated and RoCoF improved. Moreover, a possible distributed and robust parameter tuning method for PV units in multi-machine system is discussed in the paper.","PeriodicalId":425438,"journal":{"name":"2022 12th International Conference on Power and Energy Systems (ICPES)","volume":"27 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132546819","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}
