Abstract

The use of distributed generating systems, which use a renewable energy source, has experienced a fast development. Moreover their intermittent nature can be overcome using hybrid systems which combine more energy sources. This paper discusses a full experience in the realization of a hybrid plant which uses an internal combustion engine with cogeneration/trigeneration functionalities and solar source, installed in Delebio, Italy. System design aspects, with particular attention to the possible topologies and power flow control strategies are analyzed. After the analysis of design aspects, some simulation are presented to validate the proposed solution and finally experimental results of the real plant are reported.

Abstract

The use of distributed energy resources is increasing and represents a valid answer to environmental problems and to the significant costs of more traditional energy sources. The need of developing distributed energy systems is strictly related to the need of flexible and scalable high level controller, able to manage control references in order to optimise global system efficiency. This paper proposes a solution based on Real Time Linux environment, which can be applied both to single source system and to multi-source ones. A soft PLC emulator together with other software tools are provided to help application development process. The proposed control board has been developed for wind turbine applications and has been preliminary tested.

Hardware in the Loop (HIL) test bench for small-scale Distributed Generation systems

Publication Year: 2008 , Page(s): 2177 - 2182

Abstract

The paper introduces a complete study of a flexible digital control device for a very large number of low voltage power systems with functions of power quality (PQ) and/or distributed generation (DG). The novel aspect of the device is its hardware and software architecture: a modular and object oriented approach allows a high ability in adaptation to different power system topologies. In this work the authors have investigated various DG systems (wind turbine, photovoltaic generators, gas powered generating set) and different functionalities of the grid interface inverter (grid connected or stand alone operation mode). The proposed control strategy allows the definition of the power flows in order to optimize the energy source exploitation

Abstract

The use of distributed generating systems based on renewable energy sources has experienced a significant development in the last years. This paper focuses its attention on those based on photovoltaic systems. The intrinsic intermittent nature of this kind of renewable source implies the use of storage to accommodate fluctuations. The present paper proposes an hybrid solution in which photovoltaic source and gas engine are both present without storage device. With this configuration a new control technique can be used to maximizes system efficiency in both grid connection and stand alone operation mode.

Abstract

The test procedure of an electrical drive control generally requires connecting the control to the power converter, the motor and the load. This is an expensive, time and power consuming procedure especially when it is necessary to test new control algorithms or architectures as often happen in renewable energy generation power plants. This paper introduces a low power emulator of a Small Hydropower generator used to develop and test the power quality functions of a universal digital controller for distributed generation systems.
