中文摘要：
二滩水电站是雅砻江梯级开发的第一个水电站，该水电站以发电为主,是四川电网的骨干电源之一，它的运行方式的好坏,不仅影响电站自身的经济效益,而且对四川电网的安全与经济运行起着举足轻重的作用，在电力市场环境下,合理地制定该电站的年期货电量计划是二滩水电公司实现其预期效益的重要保证，因此本文重点研究了二滩水电站的年期货电量的优化问题,建立了年期货电量优化模型,以基于径流趋势预测方法选用的入库径流量为依据,用小生境遗传算法对模型进行求解,计算结果可作为该公司签订期货合同的依据。
英文摘要：
Ertan hydropower station is the first power station built on Yalong River. The station is one of the key power sources in the Sichuan electric network. The operation pattern of the station affects not only its own economic benefits but also the safety and economical operation of the whole network. In the power market, reasonable annual forward electric quantity constucted, is an important guarantee of anticipated profits of the owner ＂Ertan Hydropower Development Company＂. Therefore,the optimization of the forward electric quantity of Entan hydropower station is mainly studied with the model of optimizing annual forward electric quantity constucted Based on the forecasting inflow runoff to reservoir, the model is solved by using Niche genetic algorithm and the results can be taken as the basis for the owner to sign the forward market contract.
