问题 问答题 简答题

竞价规则的内容有那些?

答案

参考答案:

(1)电力市场监管体制的建立。内容包括电力市场监管机构的人员组成、权力与义务及隶属关系,电网调度权独立的意义。

(2)竞价模式的选择与设计。竞价模式分完全竞争与部分竞争两种。完全竞争就是不保电量的竞争,电厂的电量和电价均没有基本保证。部分竞争有两种选择:一是保基础电量的竞争,基本发电小时内电量不竞争(电价按国家规定执行),超出部分的电量竞争;二是两部制电价,如果选择两部制电价,就需制定基本电价与电量电价的合理比例和基本电价的构成。对峰谷差大、水电多的电网,可采用峰谷分时、丰枯季节电价,由于平谷段和丰水季节的电量过剩较大,此时所有水电厂参与竞争,其余时间部竞争,执行国家定价。

(3)市场竞争主体的培育。市场竞争主体包括发电厂、输配电网和用户,为此我们应制定独立发电企业的容量规模和数目限制;对电厂所发电能开始可由电网企业统一收购,但何时大用户可直接与电厂签订长期合同、何时允许独立的配电公司参与配电业务就需要考虑,同时考虑输配电业务分开经营的可能性与意义。

(4)报价方式。包括:报价的主体是以厂为单位报价,还是以发电公司为单位报价;报价的上下限。报价的时间和竞价时段的划分。

(5)特殊服务电费的制定。电厂为电网提供应急发电和黑启动电源及调峰、调频和调压等服务时,电网企业应支付的特殊服务电费的标准需要制定。

When students and parents are asked to rate subjects according to their importance, the arts are unavoidably at the bottom of the list. Music is nice, people seem to say, but not important. Too often it is viewed as mere entertainment, but certainly not an education priority(优先). This view is shortsighted. In fact, music education is beneficial and important for all students.

Music tells us who we are. Because music is an expression of the beings who create it, it reflects their thinking and values, as well ad the social environment it came influence that George Gershwin and other musicians introduced into their music is obviously American because it came from  American musical traditions. Music expresses our character and values. It gives us identity as a society.

Music provides a kind of perception(感知)that cannot be acquired any other way. Science can explain how the sun rises and sets. The arts explore the emotive(情感的)meaning of the same phenomenon. We need every possible way to discover and respond to our world for one simple but powerful reason: No one way can get it all.

The arts are forms of thought as powerful in what they communicate as mathematical and scientific symbols. They are ways we human beings “talk” to each other. They are the language of civilization through which we express our fears, our curiosities, our hungers, our discoveries, our hopes. The arts are ways we give form to our ideas and imagination so that they can be shared with others. When we do not give children access to an important way of expressing themselves such as music, we take away from them the meanings that music expresses.

Science and technology do not tell us what it means to be human. The arts do. Music is an important way we express human suffering, celebration, the meaning and value of peace and love.

So music education is far more necessary than people seem to realize.
