Power supply is difficult to meet the demand. During load peak period in summer, the proportion of air conditioning load is as high as 30% ∼ 50% This kind of load will lead to further widening the peak-valley difference and bring hidden danger to operation of power grid. This paper first introduces the interaction between users, load aggregator and grid dispatch center. Then design contract details between user and load aggregator. Two dispatching models based on contracts and direct load control are put forward in this paper, which incorporates the electric excitation and electricity price response, to ensure safe and stable operation of power grid during peak period. On the basis of grid stable operation, achieving costs optimal. Finally, solving results show that the coordinated dispatching strategy we proposed could not only effectively reduce peak load of the system but fast and precisely dispatch loads when system faults occurs.","PeriodicalId":123761,"journal":{"name":"2017 2nd International Conference on Power and Renewable Energy (ICPRE)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134047192","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}

But it cannot evaluate the degree of harmonic pollution. Under the premise of ensuring the power quality of the utility grid as well as taking the different harmonic characteristics of the harmonic source users into account, it is necessary to refine the excessive degree of harmonics out of specification. And, the harmonics evaluation should link harmonic current assessment to harmonic voltage evaluation effectively to get a better assessment result. And a method of using multi-values maybe can be adopted. Therefore, a method of harmonic assessment with multi-values considering the regulation effect is proposed in this paper. The proposed method divides the harmonics influence on power grid into seven grades, which can give the reference to the harmonic mitigation both considering the cost of harmonic governance and the effect of the harmonic mitigation. The result of the case study proves the proposed method is effective and feasible to the harmonic assessment.","PeriodicalId":123761,"journal":{"name":"2017 2nd International Conference on Power and Renewable Energy (ICPRE)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129090327","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}

An essential step to mitigate the negative effects of harmonics is to design proper filtering which in turn requires an efficient parameter estimation of a measured power system signal. In this paper a novel convex combination of the least mean mixed norm (LMMN) and recursive least square (RLS) algorithms called RLMMN is proposed for harmonic, sub-harmonic and inter-harmonic amplitude and phase angle estimation of a distorted power system signal corrupted with a random Gaussian noise. The proposed RLMMN algorithm inherits the advantages of both algorithms to achieve fast convergence, better tracking and lower steady state estimation errors. The estimation performance is evaluated for static signal and abrupt amplitude drift condition. Three other algorithms reported in the literature are considered for judging the robustness of the proposed algorithm. From the simulation studies it is observed that the proposed RLMMN algorithm exhibits superior estimation performance in terms of estimation accuracy as compared to estimations obtained by LMS, RLS and LMMN algorithms under various SNR environments.","PeriodicalId":123761,"journal":{"name":"2017 2nd International Conference on Power and Renewable Energy (ICPRE)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131754293","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}
