Traditionally, bi-level optimization problems can be solved after converting them to single-level Mathematical Problems with Equilibrium Constraints (MPEC) by Karush-Kuhn-Tucker (KKT) conditions. However, the non-convex and non-linear operating variables of the generators render KKT conditions and MPEC unavailable in strategic bidding optimization problems. To address this problem, this paper proposes a hybrid evolutionary algorithm to solve the bi-level optimization strategic bidding problem in a day-ahead electricity market with flexible demand by transforming the original lower level mixed-integer non-linear problem (MINLP) into mixed-integer linear problem (MILP). The case study result demonstrates the ability of the proposed method to solve the bi-level optimization problem and find a more profitable bidding strategy compared to the benchmark case with a competitive behaviour.","PeriodicalId":237027,"journal":{"name":"2021 5th International Conference on Green Energy and Applications (ICGEA)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124692308","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}

Having insights into electricity consumption behavior of individuals or families across the day is very useful in efficient management of electricity. In this paper, we present s study that focused on identifying patterns in the monthly electricity consumption profiles of a single household with the K-means clustering algorithm. The data required for this study was collected through a survey in the Sri Lankan context. The survey mainly captured the factors affecting electricity consumption. After proving the demand of electricity is dependable on the data that has been collected, they will be keyed into data models/ profiles that will be built using clustering algorithms. A load profile will be designed using K-means to identify usage patterns of a household on a monthly basis. The parameters that affect the electricity consumption were tested and trained using the SVM algorithm. The outcomes of this study include; identifying the factors contributing to the electricity consumption, identifying electricity consumption patterns, identifying the energy footprint of individuals or families and predicting the future electricity requirements. The results of this study provide many advantages for both consumers and suppliers in efficient management of electricity. It also provides significant impacts in both micro and macro levels through enabling efficient decision-making regarding management of electricity.","PeriodicalId":237027,"journal":{"name":"2021 5th International Conference on Green Energy and Applications (ICGEA)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123552886","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}

Therefore, a control method that can reduce the calculation time of the control system is proposed in this paper, which can obtain the optimal switching state from the 8 switching modes of the converter by judging the sector where the standard voltage vector located and the time that the instantaneous voltage control vector works.

However, existing methods combine virtual synchronous generator with classical PI control. When the voltage deviation reaches the margin value set, it still needs a certain “desaturation” time, that is, switching time. At this time, the DC voltage of the system is out of control, resulting in a large voltage fluctuation, which reduces the stability of the system. In order to solve this problem, this paper firstly analyzes the principle of virtual synchronous generator and the traditional PI control method. Then a voltage control method based on virtual synchronous generator is proposed to control the DC voltage and stabilize it in the preset voltage range. Finally, the simulation model built in PSCAD/EMTDC is used to verify the correctness of the theoretical analysis.","PeriodicalId":237027,"journal":{"name":"2021 5th International Conference on Green Energy and Applications (ICGEA)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127579996","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}
