Health Expenditure makes up a substantial part of the global economy. In the world, the costs of healthcare are increasing;patients are compelled to pay more for treatment, and that makes a lot of people faced to Catastrophic Health Expenditures (CHE) and in long run fall below the poverty line. One of the most urgent and vexing challenges faced by many low- and middle-income countries is how to provide health care for the more than two billion poor people who live in these areas (developing countries). As much as more than 65% (in 2014) of total private health care expenditure in low-income countries comes from out-of-pocket payment by patients. In addition, according to World Bank report (2007), in low and lower middle-income countries was speared nearly 13% of global health spending with 87% the global disease burden. The WHO considers health financing models with high risk pooled, such as health insurance and prepaid schemes, a promising means for achieving universal health-care coverage and promotion health care. A crucial concept in health financing is that of pooling. The WHO defines risk-pooling as the “accumulation and management of revenues in such a way as to ensure that the risk of having to pay for health care is borne by all members of the pool and not by each contributor individually”. The larger degree of pooling, the less people will have to bear the health financial risks. Furthermore, adopting and operating financing policies based on greeter risk pooling/sharing (prepayments) are recommended to all countries (especially in low and lower-middle income countries). It means risk sharing/pooling plays a key role in all financing systems for achieving effectiveness and efficiency health systems.展开更多

末端分散式资源的需求响应(demand response,DR)是支撑电力系统灵活调节的重要形式,但末端资源通常规模大且单体容量小,迫切需要虚拟电厂(virtual power plant,VPP)等市场主体进行聚合代理,从而间接参与电网公司的调节服务。聚焦于准线...末端分散式资源的需求响应(demand response,DR)是支撑电力系统灵活调节的重要形式,但末端资源通常规模大且单体容量小,迫切需要虚拟电厂(virtual power plant,VPP)等市场主体进行聚合代理,从而间接参与电网公司的调节服务。聚焦于准线型需求响应这一新兴的响应模式,重点研究VPP内部分散式资源的利益-风险互动协调策略,提出面向准线型DR的VPP两阶段优化及收益共享-风险共担决策方法,构建VPP与电网、内部用户互动协调新模式。首先,在准线型激励下VPP以整体收益最大化为目标,考虑柔性负荷响应积极度与新能源准确度因子,进行日前-日内两阶段DR优化;其次,在收益共享-风险共担决策方法下,VPP与柔性负荷共享准线型激励、与新能源共担不确定性风险,并以改进的Shapley法对内部柔性负荷进行利益分配。仿真结果表明,相较于传统DR,准线型DR给出全时段响应目标,更具有优越性;共享-共担决策吸引柔性负荷参与VPP调节,促使VPP与用户双赢。展开更多
