Transcript of "A Hybrid Power System with DC Connection at Back-Back Converters for Microgrid"

  1. 1. www.coretronix.org A Hybrid Power System with DC Connection at Back-Back Converters for Microgrid Project Objective The main object of this project is the necessity of an AC or DC Microgrid is governed by available micro sources and connected loads. Hybrid structure can ensure a sustainable configuration blending both the forms. In this paper, a hybrid Microgrid structure for a grid connected Microgrid with DC connection at back to back (B2B) converters is proposed. While a B2B connection between two AC systems could bestow a reliable, isolated and efficient coupling, an extra DC bus connection can facilitate use of the DC micro sources. Introduction The widespread interconnection of distributed generators (DGs) has created possibility of Microgrid, both in AC and DC forms. Combining both AC and DC systems, hybrid Microgrid has been proposed by many researchers. The main challenge in such micro grid structure is to manage power flows among all sources distributed in the AC and the DC grids. Suitable control schemes are proposed for such system. The coordination control algorithms are proposed in to balance the power flow between the AC and the DC grids and to maintain both the DC and the AC voltages. Software Requirements MATLAB – Simulink PSCAD Existing Method The widespread interconnection of distributed generators (DGs) has created possibility of Microgrid, both in AC and DC forms. Combining both AC and DC systems, hybrid Microgrid has been proposed by many researchers. Drawbacks: Power sharing in hybrid structure, AC and DC bus voltage stability, Power exchange between the AC and DC bus, Power quality and system reliability.

  2. 2. www.coretronix.org Proposed Method Aim: The main aim of this project is the control schemes improve the voltage stability in the DC bus and the efficacy of the controller is verified considering the uncertainty of the generators and loads existed in Microgrid. Abstract The necessity of an AC or DC Microgrid is governed by available micro sources and connected loads. Hybrid structure can ensure a sustainable configuration blending both the forms. In this paper, a hybrid Microgrid structure for a grid connected Microgrid with DC connection at back to back (B2B) converters is proposed. While a B2B connection between two AC systems could bestow a reliable, isolated and efficient coupling, an extra DC bus connection can facilitate use of the DC micro sources. Advantages The results show the efficiency of the proposed method to minimize the operation cost and emission level. A hierarchical active power management strategy for a medium voltage (MV) islanded Microgrid is proposed. The proposed scheme control the power flow of the multiple AC-DC bidirectional converters connected in parallel that connect AC and DC buses. Applications o Third party Microgrid integration to the utility with high reliability. Multiple AC DC micro grids integration at common point. o DC data centre connection to AC Microgrid and utility. o Active distribution with AC DC sources and loads.
