电力系统关键技术发展论刍议

在智能电网和能源互联网的建设和发展中,需要科学地选择不同时段的关键技术予以优先发展。利用理想电力系统的概念,基于对电力系统发展状态的评析,提出了一种系统化的电力系统关键技术发展价值分析方法,并利用所提方法对当前电力系统关键技术的发展作了简要分析。指出关键技术的优先发展不仅需要考虑技术本身对提高电力系统理想化程度的贡献,还需要综合考虑技术相互之间的促进作用和经济投入情况。当前,大数据、储能、新材料和云计算等是值得优先发展的技术方向。     

基于支持向量机综合分类模型和关键样本集的电力系统暂态稳定评估

为了提高支持向量机(Support Vector Machine, SVM)的分类性能,提出了根据关键样本集构造的SVM综合分类模型进行电力系统暂态稳定评估的方法。给出了基于不同特征量的SVM综合分类模型的构建方法、关键样本集的产生方法以及基于综合分类模型和关键样本集的SVM分类步骤。采用3机9节点典型算例和某省级电网算例进行分类效果分析。分析结果表明,所提出的基于SVM综合分类模型和关键样本集的方法,相较于传统SVM方法,大幅度减少了将不稳定样本判定为稳定的漏分类数,提高了SVM方法的实用性。所提出的基于关键样本集构造分类模型的思路对于其他数据挖掘方法也有一定的借鉴意义。

Theorizing Inside Activism: Understanding Policymaking and Policy Change from Below

To further our understanding on policymaking and policy change we need to recognize the significance of individual key actors in policy and planning processes. This article theorizes on the characteristics and policy influence of inside activism in which individual public officials act strategically from inside public administration to change government policy and action in line with a civic engagement and value commitment. Based on initial empirical findings from Swedish local government, we argue that inside activism is empirically relevant but not satisfactorily covered by other key actor concepts. We theorize that inside activism is 1) dualistic: open, deliberative, consensus-seeking and tacit, tactical, power-driven; 2) influential through informal networking inside and outside of government; and 3) dynamic as it varies over time and between critical situations. Due to current trends in society and public administration (e.g. governance), we expect inside activism to be increasingly relevant and we encourage further theoretical, empirical as well as normative research and discussion on this phenomenon.     

The commercial currency of construction framework agreements

A critique is presented of construction client–main contractor framework agreements. In the midst of an unpredictable and volatile construction environment, the commercial currency of collaborative working practice, and by extension framework agreements, is being put under increasing management scrutiny. Drawing on a literature review, the guiding principles of framework agreements are examined. A dramatic downturn in construction demand has created considerable surplus in supply. Under such conditions the buyer–supplier interdependencies become imbalanced and commercial relationships fraught. Reports by construction industry analysts demonstrate a number of private sector clients rejecting framework agreements in favour of traditional competitive procurement practices. Drawing upon a neoclassical lens, three guiding principles embedded within economic orthodoxy are employed to examine business-to-business tensions within construction framework agreements, namely, individualism, instrumentalism and equilibrium. This neoclassical interpretation of construction framework agreements reveals a potential relational management bias within mainstream rhetoric. Notably, providing a complementary account of framework agreements practice should not be construed as a rejection of collaborative working practices. An alternative account of framework agreements is presented that does not rely upon the mainstream behavioural model of contemporary contracting.
