It is shown in this paper that with both loads, time domain signals may be transformed to the Gn domain such that the resulting multivectors permit circuit analysis through rotations and dilation-contractions of the excitation signal. The power equation, in particular, is created by applying the geometric product of the voltage and current multivectors and is suitable for linear and nonlinear loads. This is in contrast to commonly used frequency analysis methods where the reactive power cannot be obtained in correspondence with its definition in the time domain and it fails at providing a unified power equation for linear and HGLs. We interpret the proposed power equation in the frequency and time domains and introduce an analogous quantity to the reactive power Q, the CN-power, for circuits with nonlinear loads. A power factor equation applicable to both loads is also presented. The resulting one-to-one correspondence between the time domain and the Gn domain avoids eliminating any component from the power equation in the time domain. Single-phase circuit examples are provided.","PeriodicalId":371843,"journal":{"name":"2010 International School on Nonsinusoidal Currents and Compensation","volume":"189 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":"133197174","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 creates a new scenario for the management of power grids, because DER increase the power capability and flexibility of the network at the expense of a higher complexity of control. If properly driven, however, PSI can improve power quality and distribution efficiency. On the contrary, every control misbehavior can cause voltage instability and/or circulation of useless currents, with the risk to affect network operation. Moreover, especially in case of islanded operation, smart grids can suffer from voltage distortion, asymmetry, and frequency variations, which may affect control accuracy and stability. In such a context, a cooperative control approach of PSI and any other electronic power processors (EPP) acting in the grid is needed, to ensure proper network operation even under severely disturbed conditions. This paper shows that the Conservative Power Theory (CPT) provides a viable background for the development of an optimum control technique of distributed EPP.","PeriodicalId":371843,"journal":{"name":"2010 International School on Nonsinusoidal Currents and Compensation","volume":"85 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":"128006403","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}

When operating in the islanded mode, smart micro-grids can also exhibit considerable variation of amplitude and frequency of the voltage supplied to the loads, thus affecting power quality and network stability. Due to the limited power capability of smart micro-grids, voltage distortion can also get worse, affecting measurement accuracy and possibly causing tripping of protections. In such a context, a reconsideration of power theories is required, since they form the basis for supply and load characterization and accountability. A revision of control techniques for harmonic and reactive compensators is also required, because they operate in a strongly interconnected environment and must perform cooperatively to face system dynamics, ensure power quality and limit distribution losses. This paper shows that the Conservative Power Theory (CPT) provides a suitable background to cope with smart grids characterization needs, and a platform for the development of cooperative control techniques for distributed switching power processors and static reactive compensators.","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":"114562717","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}
