Load Sharing Control of Parallel Inverters with Uncertainty in the Output Filter Impedances for Islanding Operation of AC Micro-Grid
Parallel connection of inverter modules is a solution to increase reliability, efficiency and redundancy of inverters in Micro-Grid system. Proper load sharing among parallel inverters is a key point. The circulating current among the inverters can greatly reduce the efficiency or even cause instability of the system. In this paper, a control strategy for improving the load sharing performance ...
متن کاملModel Predictive Control of Distributed Energy Resources with Predictive Set-Points for Grid-Connected Operation
This paper proposes an MPC - based (model predictive control) scheme to control active and reactive powers of DERs (distributed energy resources) in a grid - connected mode (either through a bus with its associated loads as a PCC (point of common coupling) or an MG (micro - grid)). DER may be a DG (distributed generation) or an ESS (energy storage system). In the proposed scheme, the set - poin...
متن کاملHierarchical Operation Strategies for Grid Connected Building Microgrid with Energy Storage and Photovoltatic Source
Abstract—This paper presents hierarchical operation strategies which are minimizing operation error between day ahead operation plan and real time operation. Operating power systems between centralized and decentralized approaches can be represented as hierarchical control scheme, featured as primary control, secondary control and tertiary control. Primary control is known as local control, fea...
متن کاملA Control Strategy for Flywheel Energy Storage System for Frequency Stability Improvement in Islanded Microgrid
The Micro-Grid (MG) stability is a significant issue that must be maintained in all operational modes. Usually, two control strategies can be applied to MG; V/f control and PQ control strategies. MGs with V/f control strategy should have some Distributed Generators (DGs) which have fast responses versus load changes. The Flywheel Energy Storage System (FESS) has this characteristic. The FESS, w...
متن کاملDynamic Modelling of a Compressed Air Energy Storage System in a Grid Connected Photovoltaic Plant
The use of photovoltaic (PV) cells in domestic and industrial applications has grown rapidly through the recent years. Constructing PV plants is a very smart measure to produce free electricity in large scales, especially in the countries with higher solar irradiation potential. On the other hand, compressed air energy storage (CAES) has already been proposed to be employed for energy storage a...
