Developing an Operation Strategy for a Hybrid Diesel-Wind-Photovoltaic System Used to Power an Autonomous and Remote Fishing Pond

Abstract

The off-grid hybrid energy systems have become a viable sustainable alternative for supplying with energy isolated autonomous farms, being more reliable options, since they have more than one electricity generation sources. This article addresses the challenges related to the configuration of a hybrid energy system composed of a wind turbine, photovoltaic panels, a diesel generator and rechargeable battery storage, which is associated with an autonomous off grid fishing pond. The first step in designing predictive control was to define consumers, their particularities in operation, and their energy demand model, then to estimate the real potential of producing renewable energy depending on the location and to create consumption models that maximize the use of power from renewable resources. A consumption management strategy has been developed for an autonomous and automatic fish pond management system, identifying optimal energy requirements for the proper operation of the needed equipment. In order to operate as much as possible using the regenerative energy resources, a prioritizing energy consumption pyramid was designed and tested and a more efficient technique of allocating energy within 24 hours of operation was defined.
