初级电网商业化运营的目标和原则是什么?

答案

参考答案:

电网商业化的初级运营即仅在开放发电市场情况下的商业化运营,其运营目标是在满足电力系统安全稳定运行的前提下,促进发电厂间竞争,提高效率,以发电成本、网损、辅助服务成本之和最低为优化目标,根据机组报价,确定发电计划,实时调度各个发电公司的机组发电,以满足负荷要求。

运营原则是在发电侧初步引入竞争机制,电力市场按照“公平、公正、公开”的“三公”原则运行,发电厂间实现保证基数电量下的有限竞价上网,保证省网统调机组完成基数电量,基数电量以内的电量以核定电价结算,剩余电量实行竞价上网;加强供电侧管理,通过对地(市)供电公司的网供电量和网供负荷计划的制定和考核,促使各地(市)供电公司做好小电厂和用户负荷的管理工作。

     Climbing a mountain is hard work. But one step (脚步) after another finally brings a person to the

top. Along the way, he can stop and look around. And the higher he climbs, the more wonderful his view

is. If he keeps climbing, he will have a new world before him. He will have a new way to see everything.

     Now learning a foreign language is something like climbing a mountain. This new language can give

you a new view of life. And it is more than a look at the surface of things. It can open the way into

people's minds and hearts and into a culture that is very different from your own culture. This will make

you richer, richer in things that money can't buy. Even though you never set foot (踏上) on a ship or a

plane, you can be an armchair traveler through books.

     The mountain climber stops now and then to enjoy the scenery around him. Reading is just like this.

If you are interested in it, you will find fun in books.
