VIETNAMESE-FARM-CLEAN-MICROGRID

项目名称：CLEANGRID（VIETNAMESE-FARM-CLEAN-MICROGRID）研究越南农业（养猪）场微电网系统的可行性，该系统采用清洁/可再生能源，包括光伏、处理过的沼气发电机和二次寿命电池作为能源储存。项目目标是提供一个负担得起的、可靠的、和清洁能源解决方案，越南农业农场，同时减轻环境污染的农场废物和不可靠/关闭-电网供电，投资回报率高。该项目的受益者是农场工人/业主和邻近社区，这些社区通常位于贫困农村/偏远/偏远地区，供电不可靠/离网。低成本和移动的能源用于基本电器，如照明，烹饪，水泵，通信，互联网接入，畜牧业在越南农业中发挥着重要作用，73%肉类产品是猪肉（2014年为2670万头）和70%的猪头（60%的猪肉产品）来自小农户/家庭农场（世行报告）。为了减轻动物废物的环境问题，通常考虑通过厌氧消化产生沼气，然后用于烹饪和发电的废物处理。因此，一个负担得起的净化沼气过程，以提高现场烹饪和发电效率，以及减少对电器的侵蚀问题是该项目的一个主要部分。该处理是基于越南当地采矿的废料（膨润土），因此是一种具有成本效益的方法。通过沼气烹饪可以改变偏远地区的木材烹饪行为，从而减少污染/森林砍伐。作为一个热带国家，越南在太阳能发电方面具有很高的潜力。然而，对于任何微电网系统来说，储能都是非常昂贵的。为了提高成本效益，越南市场上使用电动自行车/汽车二次电池的储能系统是该项目的另一个感兴趣的话题。还有，为了最大限度地提高能源转换效率和最小化能源消耗，微电网控制系统是必不可少的。电池和DC/AC逆变器模块的设计和开发方式是，它可以作为移动的模块进行拆卸，用于电力系统无法用于社区服务（如水泵）的遥远/偏远地区。为了促进规模化-微电网系统的概念与不同的功率水平和更多的可再生能源电力整合，如生物质发电，风力发电机...，建立了微网系统的能量转换损耗模型，并通过实验室试验进行了验证。此外，商业模式，包括投资成本，性能成本，投资回报率，和潜在的CO2捕获/减少的开发。

The project named as CLEANGRID (VIETNAMESE-FARM-CLEAN-MICROGRID) studies feasibility of a microgrid system with clean/renewable energy sources including PV, treated biogas generator, and secondary life battery as energy storage for Vietnamese agriculture (pig) farm.The project target is to provide an affordable, reliable, and clean energy solution to Vietnamese agriculture farm whilst mitigate the environmental pollution from farm waste and unreliable/off-grid power supply with good return of investment.The beneficiaries of the project are both the farm workforces/owner and the neighbor community where often locates in poor rural/remote/distant area with unreliable/off-grid power supply. With low-cost and mobile energy for basic appliances such as lighting, cooking, water-pump, communication, internet access, the project will address both gender and social inclusion as well as encourage equality.Livestock sector plays an important role in Vietnamese agriculture with 73% meat production is pork (26.7milion pig-head for 2014) and 70% pig-head (60% pork product) are from smallholder/householder farms (WB report). To mitigate this environmental issue from animal waste, waste process via anaerobic digestion for biogas generation and then using on cooking and power generation is often considered. Therefore, an affordable purification biogas process to improve the in-site cooking and power generation efficiency as well as reducing erosion issue on appliances is one major part of the project. The treatment is based on waste material (bentonite) from Vietnamese local mining and therefore, a cost-effective approach. The cooking via biogas could change the wood cooking behavior in the distant area leading to reduction of pollution/deforestation.As a tropical country, Vietnam has high-potential on solar power. However, for any microgrid system, energy storage is highly expensive. For cost-effective, energy storage system using secondary life battery from electric bike/vehicle in Vietnamese market is another topic of interests of the project. Also, a microgrid control system for maximizing energy conversion efficiency and minimizing energy consumption is essential.The battery and DC/AC inverter modules are designed and developed in such a way that it is detachable as a mobile module for distant/remote area where electricity system is unavailable for community service such as water-pump.To facilitate the scale-up of the microgrid system concept with different power levels and more renewable energy power integration such as biomass power generation, wind-turbine..., an energy conversion loss model for microgrid system is developed and validated via in-lab test. Also, a business model including investment cost, performance cost, return on investment, and potential CO2 capture/reduction is developed.
