[IEEE 2018 IEEE Industry Applications Society Annual Meeting (IAS) - Portland, OR, USA (2018.9.23-2018.9.27)] 2018 IEEE Industry Applications Society Annual Meeting (IAS) - Design and Control of Solar PV-Pico Hydro Based Microgrid
摘要： This study deals with a solar photovoltaic (PV) and pico-hydro based microgrid having a battery energy storage (BES), which transfers uninterruptable power across voltage source converter (VSC) at the common coupling point (CCP). Only one VSC in this system, has the competency to eradicate the power quality problems, compensation of harmonics current, regulation of frequency and voltage under varying loads. A battery energy storage (BES), which is coupled directly to the DC bus, manages the power flow under the changes in loading and variable power generation. A synchronous reluctance generator (SYRG) for pico-hydro generation is used because of its reliability, and cost-effectiveness than other such as permanent magnet brushless generators synchronous generator. The SRFT (Synchronous Reference Frame Theory) control is used to control the system frequency and voltage at PCC. The proposed system uses an INC (Incremental Conductance) technique for extraction of maximum power from a PV array. The smooth performance of the microgrid under various operating conditions, is demonstrated through experimental results, which meet power quality requirement of the IEEE 519 standard.

Robust 3IMPL Control Algorithm For Power Management of SyRG/PV/BES Based Distributed Islanded Microgrid
摘要： In an islanded AC microgrid, a comprehensive algorithm of three phase, improved magnitude, phase locked loop (3IMPL) control algorithm is developed to provide DC off set removal, steady state error removal and fast dynamic response. In addition, the control of the voltage source converter (VSC) using 3IMPL algorithm, provides voltage and frequency control and elimination of harmonics of nonlinear loads. In proposed microgrid, a solar PV array is connected to the DC link through a boost converter and an INC (Incremental Conductance) technique is used for extraction of maximum power from a PV array. Due to intermittency of PV array, a synchronous reluctance generator (SyRG) is used for pico-hydro generation because it is economical, ecologically sustainable, requires less maintenance and extremely reliable. Moreover, a microgrid suffers from problems of variation in generation and continuous load fluctuations, therefore for power balancing between the source and the load, a storage battery is connected across the DC link of VSC through a bidirectional DC-DC converter. Test results on a prototype have verified the control strategy and it is able to improve the power quality of the system at varying solar insolation and unbalance in loads.
