It is ascertained that compensating the alternative parts of the instantaneous active and reactive powers leads to a sinusoidal power source current only under sinusoidal voltage conditions. The mathematical demonstration is found and it is verified on some practical examples. It is shown that the difference between Akagi's active current and the true active current is very small for operation under real conditions of voltage total harmonic distortion factor below 10%. A modified definition of the active component of the current is proposed for operation under nonsinusoidal voltage conditions. The DC motor and full control rectifier driving system is used as a case study. Finally, a mathematical inconsequence that put under uncertainty the p–q theory correctness under nonsinusoidal voltage conditions is pointed out.","PeriodicalId":371843,"journal":{"name":"2010 International School on Nonsinusoidal Currents and Compensation","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132165907","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}

These converters can be used for connecting renewable energy sources (solar, wind, and others) to the micro-grids or for harmonic, reactive power or unbalance compensation, and even for voltage regulation. The emphasis is given on the compensation characteristics derived from the p–q Theory, and simulation results of test cases are shown. Special attention is put on the oscillating component of the instantaneous real power, as it may produce torque oscillations or frequency variations in weak systems (micro-grids) generators. This oscillating component, as defined in the p–q Theory, gives the amount of oscillating energy between the source and the load, and its compensation through a switching compensator must have an energy storage element to exchange it with the load. With the p–q Theory this energy storage element can be easily calculated as a function of the average component of the instantaneous real power, which depends on the observation period.","PeriodicalId":371843,"journal":{"name":"2010 International School on Nonsinusoidal Currents and Compensation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128440491","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}
