In this paper, the effect of changes in incentives and penalties on the implementation of I/C service on the microgrid is studied considering different uncertainties. The microgrid studied in this paper can exchange power with the upstream network. Effect of implementing I/C service in different modes on operation cost, customer profit, load factor, and peak reduction is evaluated in this paper.

One way to solve such unbalance is to have DGs that can compensate for the load unbalance by being able to dispatch unbalance power. In this work, single-phase controlled PQ inverter interfaced DGs are modeled for this purpose. A detailed control model of the single-phase PQ inverter is derived from which we approximate the power stage of the inverter to a voltage-controlled source. Simulation studies in PSCAD showed that the voltage-controlled model gives an accurate representation of the elaborate switching model of the single-phase PQ inverter. Coordination of unbalanced power dispatch is realized by stacking the single-phase inverter in a manner similar to the three-bridge four wire shunt active filter and dispatch setpoint are sent to the PQ inverters from the secondary and tertiary control level of the microgrid for load compensation purpose. Case studies of balanced, unbalanced and load compensated systems are presented and evaluated with two unbalance indices: phase voltage unbalance rate (PVUR) and true voltage unbalance factor (VUF). The studies showed that in an islanded microgrid with a non-stiff reference source, the primary source of voltage unbalance across three phase nodes is unbalanced loading and that by dispatching unbalanced power to the PQ inverters to compensate for load unbalance, a significant improvement in system balancing could be realized.","PeriodicalId":424038,"journal":{"name":"2019 IEEE Texas Power and Energy Conference (TPEC)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125660618","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 modern power systems with multiple interconnected control areas (CA), altering the generation-demand does not only affect the system frequency but also leads to undesired deviations in power flows between CAs. To avert the catastrophic failure of the entire system, generation must always balance out the load demand so as to maintain frequency and tie-line power within prescribed limit. Thus, load frequency control (LFC), achieved by adjusting the MW outputs of generators, is applied. In this paper, model predictive control (MPC) based LFC in multi-area power system (MAPS) is presented. It is aimed at maintaining frequency of each CA and tie-line power within given limits. The conventional LFC is modified to consider the effect of incremental control action, in addition to the system dynamic constraints like generation rate constraint (GRC). The effectiveness of the proposed scheme is verified through time-based simulations on 8-generator, 4-area MAPS subjected to multiple load disturbances. The responses of the system is compared with traditional PID controller. The results reveal efficacy of the proposed scheme with 26.79% and 25.12% improvement of settling time and overshoot respectively over the PID controller.","PeriodicalId":424038,"journal":{"name":"2019 IEEE Texas Power and Energy Conference (TPEC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115602073","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}
