Compared with other control strategies, configuring MPC can achieve the purpose of system optimization, which is to enhance the stability of a power system with DFIG.

Using the damping effect of load to simulate the response of load to frequency deviation plays an important role in system frequency response. Usually, the damping coefficient of load is considered as a constant, which can not be adjusted, and is usually measured by practice. This paper studies the effect of electrolytic aluminum with large industrial load on frequency response of power grid. Electrolytic aluminum load is a voltage-driven DC load, which has no frequency response, but has large load capacity and great adjustable potential. Based on this, this paper studies a load damping control method, which responds to the system frequency change by controlling the saturable reactor. The simulation results verify the effectiveness of the proposed control method.","PeriodicalId":356667,"journal":{"name":"2021 3rd Asia Energy and Electrical Engineering Symposium (AEEES)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134418251","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 study, we formulate the demand response problem in the smart grid as a bi-level game: a Stackelberg game between retailers and consumers and a noncooperative game among consumers.

In order to effectively deal with the wind power uncertainty and accommodate more wind energy, the problems faced by the power system include how to determine the boundary of the admissible region (AR) of wind power and how to measure the risk when wind power exceeding the AR. This paper proposes a robust unit commitment model considering the conditional value-at-risk (CVaR) of wind power integration. Based on the cost/benefit analysis, the wind AR on each node can be obtained by simultaneously optimizing the operation cost and CVaR cost. In the model, generation reserve, short-term ramping reserve, and transmission reserve are involved to guarantee the system security. The proposed model is recast into a mixed integer linear programming problem based on piecewise linear approximation and Soyster's robust linearization technique. The effectiveness and validity of the proposed method are illustrated on the IEEE-RTS system.","PeriodicalId":356667,"journal":{"name":"2021 3rd Asia Energy and Electrical Engineering Symposium (AEEES)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133079462","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}

However, with the large number of renewable energy stations and charging stations connected into multi-station integration systems, the uncertainties and volatilities of new energy output and charging time of charging stations adversely affect the economic, efficient, and stable operation of the system. To achieve the economic, efficient, and stable operation of multi-station integration energy system, this paper establishes an integration station model with five stations in one: substation, charging station, energy storage station, data center station and renewable energy station. This paper adopts Monte Carlo simulation method to obtain renewable energy station output scenarios and K-means algorithm to perform scenario reduction. Probability density function is used to describe the uncertainty of random charging at charging station. Considering time-of-use price, a multi-objective optimization model is established with respect to costs and risks. NSGA-II and multi-attribute decision method are combined to find the optimal solution. The simulation results show that the proposed method significantly reduces the total operating cost and risk of the system, indicating that the proposed model and method are feasible.","PeriodicalId":356667,"journal":{"name":"2021 3rd Asia Energy and Electrical Engineering Symposium (AEEES)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130091330","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}

This paper is to propose an on-line stability analysis and active control method for large-scale wind power systems to prevent the sub/super-synchronous oscillation. At first, two-input two-output (TITO) system model and multi-input multi-output (MIMO) system model are presented for wind farm system, as well as the corresponding stability analysis approach. Then, an active control strategy for wind farm systems to prevent oscillations are proposed, which contains system level control and farm level control.

This article proposes typical control methods such as master-slave and droop for low-voltage AC/DC hybrid systems, and builds its test platform. The test environment which is close to real operating conditions is composed of renewable energy access modules, power distribution configuration modules and other components. Research on the coordinated control method of AC/DC hybrid renewable energy systems has been carried out on the test platform.
