[HCG25-05] Energy management system development in agriculture and fisheries
Keywords:Renewable energy, Energy storage, EMS, Food production
When constructing a closed ecosystem, it is necessary not only to arrange material circulation, but also to maintain the system independently in terms of energy. In such a case, since it is very costly to transport fuel from the earth in space, energy procurement that does not rely on fuel, i.e., the use of renewable energy, is required. On the other hand, there is a concept of building a micro-grid that is self-sufficient in energy in an area with renewable energy, mainly solar power (hereafter, PV), on remote islands that are not connected to a large-scale electric power grid even on Earth. In this presentation, we would like to discuss issues that need to be resolved in order to build a microgrid with renewable energy as the main power source.
Since the output of PV and wind power generation fluctuates and the grid becomes unstable when the supply and demand of electricity do not balance, it is important to develop not only energy storage technology but also demand response (DR) technology to control electricity demand in accordance with power generation in order to adjust the balance between supply and demand of electricity. For example, it is common for plant factories to provide an ideal environment for plant growth, but for DR, technologies have been developed to adjust the operation of LEDs, air conditioners, and culture medium circulation pumps. Thus, energy management systems (EMS) are being developed to control power consumption by controlling the operation of equipment.
In order to construct a microgrid, it is necessary to develop an EMS for each facility, such as a plant factory, as well as an autonomous decentralized energy system that manages energy for the entire area. In rural areas, a Village EMS (VEMS) has been developed to manage the energy of agricultural and fishery facilities in the area; the VEMS manages information on energy surpluses and shortages at each facility and issues DR commands to each facility to balance supply and demand in the area. VEMS also grasps information on production at each facility and, in some cases, controls the amount of shipments. Furthermore, VEMS communicates with other EMSs, such as residential EMSs, to balance energy supply and demand in the area.
Microgridization is particularly needed in remote islands without power grids and in remote areas where power transmission costs are high, and research is underway. The results of those studies are expected to be applied in the construction of closed ecosystems in outlying areas.
