Analysis of System Value Evolution Trends of Energy Storage in Decarbonization Process

With the continuous expansion of the scale of renewable energy installation,the demand for energy storage has increased significantly.However,there are significant differences in the value of energy storage in different scenarios,and the phenomenon of diminishing marginal benefits of energy storage is becoming more apparent.Therefore,themulti-dimensional value evolution trend of energy storage has become a key issue.This study selects indicators from three dimensions of energy storage:low-carbon emission reduction,smoothing wind and solar power fluctuations,and saving generation costs,quantifying the economic,environmental,and technical values of energy storage.This forms a quantitative evaluation system for energy storage value.By comparing the calculated system values under different energy storage capacities,the marginal value evolution trend of energy storage is obtained.Meanwhile,considering factors such as the utilization rate of renewable energy,the change in energy storage value under different scenarios is analyzed.The results show that the value of long-duration energy storage is significantly affected by the energy storage capacity.Specifically,when the charge-discharge efficiency of longduration energy storage reaches 0.6 or above,the system value increases significantly.Additionally,appropriately reducing the cost of energy storage capacity also helps to improve its system value.

Research on Traditional Village Protection Development Planning Based on Value Characteristics——Taking Heshe Village in Jiangxi Province As An Example

Traditional villages are the foundation of human history, the crystallization of agricultural civilization, the important carder of homeland feelings, and the spiritual homeland of the Chinese nation. In the important period of attaching importance to the protection of traditional villages and making active plans for the protection and development of traditional villages, the planning of conservation has been stereotyped, which only cares about quantity and speed. Every traditional village has its unique value and soul, and ignoring its internal cultural connotation and value characteristics can result in the lack of scientific and comprehensive planning, making it unable not be implemented in practice. In this paper, taking Heshe Village in Jiangxi Province as an example, the value characteristics oriented planning strategy for traditional villages were proposed through the refinement of its value characteristics based on the scientific planning principles.

Change in Ecosystem Service Value Arising from Land Consolidation Planning in Anhui Province

The evaluation of change in ecosystem service value arising from land consolidation planning is an important aspect of environmental impact assessment of land consolidation. By estimating the change in ecosystem service value before and after the implementation of land consolidation planning, it is able to quantitatively describe the change in ecosystem service value arising from land consolidation planning, so as to provide a quantitative basis for the environmental impact assessment of land consolidation. Taking the case of Anhui Province, the authors developed the equivalency factor table of ecosystem service value, to determine the economic value of single equivalency factor of ecological service value in the study area, calculate per unit area of ecological service value of land ecosystem in the study area, and research the change in ecosystem service value before and after the implementation of land consolidation planning in Anhui Province. The results show that after the implementation of a new round of land consolidation planning in Anhui Province, the total ecosystem service value may decrease to some extent, the farmland ecosystem service value substantially increases, while water body ecosystem service value greatly decreases.

The Optimal Inventory Policy for Reusable Items with Random Planning Horizon Considering Present Value

We discuss five areas of inventory model, including reusable raw material, EPQ model, optimization, random planning horizon and present value. In the traditional EPQ model, the stock-holding cost of raw material was not counted as a part of relevant cost. We explored the possibility of reducing a company’s impact on the environment and increasing their competitiveness by recycling their repair and waste disposal. The products are manufactured with reusable raw material. Our analysis takes into account the time value, and the present value method is applied to determine the optimal inventory policies for reusable items with random planning horizon. Results show how the heuristic approach can achieve global optimum. Numerical examples are given to validate the proposed system.

Topological Order Value Iteration Algorithm for Solving Probabilistic Planning

AI researchers typically formulated probabilistic planning under uncertainty problems using Markov Decision Processes (MDPs).Value Iteration is an inef?cient algorithm for MDPs, because it puts the majority of its effort into backing up the entire state space, which turns out to be unnecessary in many cases. In order to overcome this problem, many approaches have been proposed. Among them, LAO*, LRTDP and HDP are state-of-the-art ones. All of these use reach ability analysis and heuristics to avoid some unnecessary backups. However, none of these approaches fully exploit the graphical features of the MDPs or use these features to yield the best backup sequence of the state space. We introduce an improved algorithm named Topological Order Value Iteration (TOVI) that can circumvent the problem of unnecessary backups by detecting the structure of MDPs and backing up states based on topological sequences. The experimental results demonstrate the effectiveness and excellent performance of our algorithm.

用于移动机器人路径规划的改进强化学习算法

针对传统Q-learning算法规划出的路径存在平滑度差、收敛速度慢以及学习效率低的问题,本文提出一种用于移动机器人路径规划的改进Q-learning算法。首先,考虑障碍物密度及起始点相对位置来选择动作集,以加快Q-learning算法的收敛速度;其次,为奖励函数加入一个连续的启发因子,启发因子由当前点与终点的距离和当前点距地图中所有障碍物以及地图边界的距离组成;最后,在Q值表的初始化进程中引入尺度因子,给移动机器人提供先验环境信息,并在栅格地图中对所提出的改进Q-learning算法进行仿真验证。仿真结果表明,改进Q-learning算法相比传统Q-learning算法收敛速度有明显提高,在复杂环境中的适应性更好,验证了改进算法的优越性。
