This paper proposes an artificial neural network (ANN)-based energy management system (EMS) for controlling power in AC–DC hybrid distribution networks. The proposed ANN-based EMS selects an optimal operating mode by collecting data such as the power provided by distributed generation (DG), the load demand, and state of charge (SOC). For training the ANN, profile data on the charging and discharging amount of ESS for various distribution network power situations were prepared, and the ANN was trained with an error rate within 10%. The proposed EMS controls each power converter in the optimal operation mode through the already trained ANN in the grid-connected mode. For the experimental verification of the proposed EMS, a small-scale hybrid AD/DC microgrid was fabricated, and simulations and experiments were performed for each operation mode.

Agricultural Operation

Ecological civilization construction and rural revitalization is a strategic decision made by the central government to solve the problems of ecological protection and rural sustainable poverty alleviation. At present, the dominant agricultural operation modes in China can be roughly divided into three types: family farm mode, agricultural enterprise mode and cooperative mode. Practice has proved that different agricultural operation modes have different effects. In ecological fragile areas, how to adopt agricultural operation modes can not only promote agricultural prosperity and increase farmers' income, but also protect the ecological environment and promote the coordinated development of ecology and economy needs further analysis. Based on the current rural revitalization strategy and ecological protection background, this paper analyzes the operation mechanism of agricultural operation mode from the principal-agent and ecological land rent theory, and analyzes the development dimensions of advantageous agriculture of various modes. On the basis of rural and farmers, this paper provides references for the selection of agricultural operation mode in different regions. There are many factors that need to be considered in the choice of agricultural operation mode in ecological fragile area. In the future, each region should conduct analysis and treatment according to its own actual situation.

Planetary Gears

Modern hybrid electric vehicles (HEVs) like the fourth generation of Toyota Prius incorporate multiple planetary gears (PG) to interconnect various power components. Previous studies reported that increasing the number of planetary gears from one to two reduces energy consumption. However, these studies did not compare one PG and two PGs topologies at their optimal operation. Moreover, the size of the powertrain components are not the same and hence the source of reduction in energy consumption is not clear. This paper investigates the effect of the number of planetary gears on energy consumption under optimal operation of the powertrain components. The powertrains with one and two PGs are considered and an optimal simultaneous torque distribution and mode selection strategy is proposed. The proposed energy management strategy (EMS) optimally distributes torque demands amongst the power components whilst also controlling clutches (i.e., mode selection). Results show that increasing from one to two PGs reduces energy consumption by 4%.
