On-Site Energy Consumption Technologies and Prosumer Marketing for Distributed Poverty Alleviation Photovoltaic Linked to Agricultural Loads in China

In China, photovoltaic poverty alleviation projects play important role in promoting social and economic development in poverty-stricken areas. They can help stabilizing and increasing incomes of the poor. However, poverty alleviation photovoltaics are mainly connected to the rural distribution network in large numbers, which have a greater impact on the safe and stable operation of the distribution network, making the rural distribution network difficult to solve the problem of collecting and consuming distributed photovoltaic energies on-site. Meanwhile, photovoltaic poverty alleviation projects mainly rely on subsidies from the government and power grids, and the prosumer marketing methods are inadequate. In this paper, an effective on-site consumption technology for photovoltaic power generation linked to agricultural load for poverty alleviation is discussed, together with new energy management and planning technologies for stable two-way energy flow between photovoltaic power generation and rural distribution networks, which can increase the photovoltaic power supply radius, and deal with load fluctuations, and perform precise reactive power control of agricultural load. Furthermore, a prosumer marketing that can simultaneously create maximum economic benefits for power grid and poverty alleviation targets is proposed. The detailed economic benefits are calculated for a demonstration project in Funan county, Anhui province, China.
