An Integrated Image Task Planning in Satellite Networks:From Instruction Release and Observation Perspective

The unreasonable observation arrangements in the satellite operation control center(SOCC)may result in the observation data cannot be downloaded as scheduled.Meanwhile,if the operation instructions released by the satellite telemetry tracking center(STTC)for the on-board payloads are not injected on the specific satellites in time,the corresponding satellites cannot perform the observation operations as planned.Therefore,there is an urgent need to design an integrated instruction release,and observation task planning(I-IRO-TP)scheme by efficiently collaborating the SOCC and STTC.Motivated by this fact,we design an interaction mechanism between the SOCC and the STTC,where we first formulate the I-IRO-TP problem as a constraint satisfaction problem aiming at maximizing the number of completed tasks.Furthermore,we propose an interactive imaging task planning algorithm based on the analysis of resource distribution in the STTC during the previous planning periods to preferentially select the observation arcs that not only satisfy the requirements in the observation resource allocation phase but also facilitate the arrangement of measurement and control instruction release.We conduct extensive simulations to demonstrate the effectiveness of the proposed algorithm in terms of the number of completed tasks.

Cyber-physical Integrated Planning of Distribution Networks Considering Spatial-temporal Flexible Resources

The rapid development of cyber technology and the increase of flexible resources have transformed the distribution network into a cyber-physical distribution system,while the accompanying multidimensional uncertainties have brought new planning challenges.In this paper,an innovative approach is proposed to effectively leverage distributed resources while considering the impact of cyber-physical coupling in distribution network planning.A cyber-physical integrated planning model of the distribution network is proposed,considering the effects of spatial-temporal flexible resources and multi-network coupling.Specifically,a three-layer optimization model is established and analyzed by the simulate anneal-particle swarm optimization algorithm.The upper layer achieves the optimization of the location and configuration of energy storage systems and smart terminal units.The middle layer optimizes the data load migration strategy using spatial-temporal flexible resources to solve the voltage exceeding problem caused by high penetration of distributed power access,while the lower layer optimizes the cyber side communication topology,improving the convergence speed and control performance of the distribution network.Then,the optimization model is analyzed iteratively with objective functions including total planning cost,operation excess loss and distributed control performance.Finally,the effectiveness and economy of the proposed planning scheme is verified and compared to traditional methods.

Integrated resources planning in microgrids considering interruptible loads and shiftable loads

Demand response has the potential to bring significant benefits to the optimal sizing of distributed generation(DG) resources for microgrids planning. This paper presents an integrated resources planning model considering the impact of interruptible loads(ILs) and shiftable loads(SLs) in microgrids, which simultaneouslydeals with supply side and demand side resources and minimizes the overall planning cost of the microgrid. The proposed model can be applied to offer a quantitative assessment how IL and SL can contribute to microgrid planning. The pure peak clipping model with IL and SL is also provided for comparisons. Moreover, sensitivity analysis of parameters in the model is performed.Numerical results confirm that the proposed model is an effective method for reducing the planning cost of microgrids. It was also found that the major contributing factors of IL and SL have great impact on the economic benefits of the proposed model in low-carbon economy environments.

Energy Planning Considering the Policy Dimension Seeking for Sustainable Development

The objective of this work is to analyze the intrinsic aspects for policy dimension inside the energy planning and energy long term sustainability. In that sense, the methodology intends to take the Brazilian example as a case study and offer a somewhat unorthodox perspective on the subject of State energy planning. This matter is, beyond a purely technical question or a problem for the field of exact sciences, a point of primary interest to the field of social and human sciences. More the backbone methodology in this research is the Integrated Energy-Resources Planning (IRP), chosen for its ability to integrate both the supply and demand perspectives in the discussions about energy planning [1] [2]. A historical perspective is a guideline to approach issue: starting at the early Twentieth century, this study covers the major landmarks of the country energy concern to the present day;particularly noteworthy are the implications of the realpolitik—that is, the elements in politics that are developed within the institutional frameworks, such as governmental plans and decisions. As a result, it presents a complex picture, which we try to understand from the perspective of supply and demand integration. The originality of the study lies in the refusal to accept fallacious technical statements, as we consider the issue primarily a human and social problem, but considering the validity of technical statements that are correct.

Modeling Assessment of Renewable Energy to Design Business Plans of Power Options Aimed Energy Planning

The objective of this paper is the evaluation of business opportunities attractiveness in RER （renewable-energy resources） within a specific geographic area, and using some concepts of integrated energy-resource planning. The proposed methodology includes the main figures of economic merit evaluated to each resource assessed, the sensitivity analysis on cash flow, and recommendations of investments to each energy option assessed. A study case is applied within the northwest region of Sao Paulo State （Brazil） for those renewable-energy options. Five options of renewable-energy resources were chosen to be evaluated： three ERs （energy resources） from supply side （small hydro, wind farms and sugarcane bagasse） and two ERs from demand side （replacement of incandescent lighting by fluorescent and replacement of electric showers by central heating systems）. The conclusion is that, only two assessed ERs that have received investment grade were sugarcane biomass and fluorescent lamps replacing incandescent lamps. The rest have restriction due different reasons listed.

Energy Integration in South America Region and the Energy Sustainability of the Nations

The objective of this manuscript is to analyze relation involving the energy sector and socioeco-nomic growth and, then, contextualize the process of energy integration within the development policies in South America. The methodology considers data related to the world’s economy and energy consumption and energy integration policy in countries and regions;and, South America’s energy potential and the energy integration process. Results show that despite the political and institutional difficulties involving the process, energy integration can bring a lot of benefits for countries development. The process of energy integration in South America is divided in three moments, but in both periods the transnational energy projects were restricted, mostly, by a bi-lateral plan and the creation of physical links in a region. In the 21th century’s context, it should be noted Brazil’s participation which has been consolidated as a lead country in this process, and, also the IIRSA (Initiative for the Integration of Regional Infrastructure in South America, nowadays renamed as COSIPLAN) like the main initiative in energy integration in the continent, in a context where the projects are no longer limited to traditional economic blocs. Finally, we note a lack of consensus in defining a comprehensive model of integration and solving asymmetries both within countries and between them.

矿产资源规划与国土空间规划衔接的探讨

在构建国内国际双循环背景下,我国矿产资源主要来源和终端产品流向形成两头在外的格局。国土空间规划应考虑矿产资源在双循环体系下的定位,为矿产资源保护开发留下空间,确保“两个市场、两种资源”的联动。本文梳理了自然资源统一管理要求下,国土空间规划、矿产资源规划、矿业权设置区划三个层次规划管理工具的逻辑关系,指出构建国内国际双循环必然要求矿产资源国内开发和国际贸易联动,国土空间规划应当为矿产资源安全联动提供国内矿产资源开发空间。基于矿产资源的经济价值和生态价值,本文提出不同国土空间下、不同特点矿产资源分层次的保护和利用原则,为构建国土空间规划、矿产资源规划、矿业权设置区划三个层次的空间治理体系提供建议。
