Energy is closely related to the overall progress of society and the overall development of mankind. The two major problems of energy shortage and environmental pollution caused by long-term energy use have been plagued by scholars at home and abroad. The proposal of the Energy Internet aims to improve energy utilization efficiency, reduce energy waste, optimize energy allocation, and thereby alleviate environmental pollution.Therefore, the research on energy internet management is of great significance. Starting from the cooperative game theory, this paper combines the Shapley value with energy Internet management, and establishes a model to solve the problem of the distribution of excess profits caused by the joint work of the Energy Internet Alliance, and provides a new research perspective for energy Internet management.

Sensing Data

Quality monitoring is important for farmland protection. Here, high-resolution remote sensing data obtained by unmanned aerial vehicles (UAVs) and long-term ground sensing data, obtained by wireless sensor networks (WSNs), are uniquely suited for assessing spatial and temporal changes in farmland quality. However, existing UAV-WSN systems are unable to fully integrate the data obtained from these two monitoring systems. This work addresses this problem by designing an improved UAV-WSN monitoring system that can collect both high-resolution UAV images and long-term WSN data during a single-flight mission. This is facilitated by a newly proposed data transmission optimization routing protocol (DTORP) that selects the communication node within a cluster of the WSN to maximize the quantity of data that can be efficiently transmitted, additionally combining individual scheduling algorithms and routing algorithms appropriate for three different distance scales to reduce the energy consumption incurred during data transmission between the nodes in a cluster. The performance of the proposed system is evaluated based on Monte Carlo simulations by comparisons with that obtained by a conventional system using the low-energy adaptive clustering hierarchy (LEACH) protocol. The results demonstrate that the proposed system provides a greater total volume of transmitted data, greater energy utilization efficiency, and a larger maximum revisit period than the conventional system. This implies that the proposed UAV-WSN monitoring system offers better overall performance and enhanced potential for conducting long-term farmland quality data collection over large areas in comparison to existing systems.

Abstract An autonomous adaptive MPC architecture is presented for control of heating, ventilation and air condition (HVAC) systems to maintain indoor temperature while reducing energy use. Although equipment use and occupant changes with time, existing MPC methods are not capable of automatically relearning models and computing control decisions reliably for extended periods without intervention from a human expert. We seek to address this weakness. Two major features are embedded in the proposed architecture to enable autonomy: (i) a system identification algorithm from our prior work that periodically re-learns building dynamics and unmeasured internal heat loads from data without requiring re-tuning by experts. The estimated model is guaranteed to be stable and has desirable physical properties irrespective of the data; (ii) an MPC planner with a convex approximation of the original nonconvex problem. The planner uses a descent and convergent method, with the underlying optimization problem being feasible and convex. A year long simulation with a realistic plant shows that both of the features of the proposed architecture - periodic model and disturbance update and convexification of the planning problem - are essential to get performance improvement over a commonly used baseline controller. Without these features, long-term energy savings from MPC can be small while with them, the savings from MPC become substantial.

Energy Options

Long-term limits to growth in energy-use will be imposed not by inability to expand supply but by the rising environmental and social costs of doing so. These costs will therefore be central issues in choosing long-term energy options. Energy from nuclear fusion, like solar energy, is not one technology but many. Some of the fusion possibilities seem likely to have very attractive environmental characteristics; others may be little better in these regards than nuclear fission.Issues in fusion-reactor design that are crucial from the environmental standpoint include: size of tritium inventory and pathways for its release; nature and configuration of materials that are subject to neutron activation; forms and quantities of the stored energy that are internal to the reactor, and the nature of potential links between fusion technology and nuclear weaponry.

Historically, energy utilization efficiency has been measured using energy ratio and energy productivity. Both these measures have their limitations. So a new measure of energy productivity, i.e. the value of product per unit of energy input, is proposed to measure energy utilization at macro levels. This measure will enable comparison of the efficiency of different agricultural systems, agricultural regions, farm size classes, countries, etc. Comparisons over time of the changes within an agricultural system are also possible, even if the product mix changes. It will help in Identifying regions of comparative advantage for various agricultural activities, and may also aid policy formulation for the location of agriculture and agricultural development. This measure of efficiency is a midway approach to net energy analysis and traditional economic analysis.

Efficient Energy Use

The efficient use of energy is the key to maintaining our world’s resources; indeed our future depends on it. Energy conservation can be achieved through increased efficient energy use, in connection with decreased energy consumption and reduced consumption from conventional energy sources. Energy conservation can result in increased financial capital, environmental quality, national security, personal security, and human comfort. Individuals and organizations that are direct consumers of energy choose to conserve energy to reduce energy costs and promote economic security. In view of the nation's energy security interests, it is important to be increasing alternative fuel capability throughout the fleet. The need to ensure the nation's long-term energy security is of such vital concern that it takes precedent over possible short-term convention energy sources consumption and environmental impacts.
