水电厂上网电量结构优化策略研究

Study on optimized structure of hydropower generation amount in system

发电厂上网电量和上网报价的策略

Strategy of Power Generation Amount to Network and Quotation to Network for Power Plants

并以某水电厂2002年历史数据为例进行分析对比，得出了水电厂在实行丰枯电价政策的条件下进行上网电量结构优化的策略。

The optimized structure of hydro power generation amount in system is carried out under different flood and dry power price by an example of analyzing the historical data of a hydropower plant in 2002 .

造成这一现象的原因是小水电规模较小、输出成本较高，运行和管理水平落后，缺乏公平的上网电量和上网电价以及政策支持有限等。

The reasons are small scale of small hydropower , high cost of electricity transformation , poor operation and management and unfair prices of electricity sold to grid and customer and lacking of favorite policy support .

发电机组个别的合约电量的电价值和市场竞争产生的上网电量的电价值形成发电机组自身的盈亏分布状况，是指导发电机组进行日前市场交易报价的辅助工具。

The electricity value of some contracts and the interconnected electricity value obtained through competition cause the profit / loss distribution of units , which acts as a supporting tool to guide the day-ahead bidding of units .

初级电力市场中，将发电公司的一定比例的月度预上网电量进行竞价交易，从而使竞价成功的发电公司得到了部分竞价电量。

In primary electricity market a certain proportion of monthly generated electricity quantities of generation companies are allocated to bidding transaction , thus , the generation companies which succeed in generation bidding can obtain a portion of bidding electricity quantity .

另一方面，通过对比平均调度与节能发电调度模式下上网电量的分配状况，分析开发商投资可再生能源与燃煤发电的经济与社会效益水平。

On the other hand , comparing allocation position of the grid electricity in average scheduling mode with that in energy-saving power generation scheduling mode , this paper analyzed economic and social benefits of investing in renewable energy and coal-fired power .

研究结果表明，当电量市场需求小于等于每个发电厂商的申报上网电量时，发电厂商的最优报价将围绕其单位发电成本与电力市场最高限价之间的平均值小幅波动；

The result shows that when the power market demand is less than or equal to supply of every power plant , the optimal quoted price of every power plant is close to the average value between its unit generation cost and the greatest limited price ;

目前，国内各区域电网发电企业参与竞价上网的电量基本上占总发电量的10%左右，但这一比例还有提高的空间。

Now , bidding electrical quantity to Power generation enterprises occupies about 10 % among total annual produced electricity , and it has more possibility to increase in future .

最后，对某梯级水电厂以收益最大为目标进行分析计算，得出了在竞价上网条件下的电量优化策略。

Accordingly , a hydropower plant with maximum profits as the objective is analyzed and calculated so as to obtain the optimal structure tactics of electricity quantities in the case of the competitive price of listing power network .

发电企业之间的竞争从表面上看是上网电价和上网电量的竞争、成本的竞争，而本质上是管理的竞争，其中人力资源是竞争的决定力量。

That the competition between electric power generation enterprise competes from looking at competition , cost being to get on the Internet electrovalence and to get on the Internet quantity of electric charge superficially , is administrative competition but essentially , human resources among them are the decision strengths competing .

火力发电企业在难以提高上网电价或增加上网电量的情况下，提高经济效益的可行途径就是提高管理水平、降低发电成本。

It is difficult for the thermal power enterprises to raise the surfer electricity price or increase the surfer electricity quantity , in which case upgrading the management and lowering the power generating cost become feasible to improve the economic performance .

为争取成功地上网发电并取得最大经济效益，电厂需要研究优化的竞价策略，分析上网报价的电量-电价曲线模型。

So the bidding strategy should be studied to gain maximal profits and the power quantity-power price curve model of bidding should be analyzed .
