In electrical grid; when the demand power increases energy prices increase, when the demand decreases energy prices decrease. For this reason; to increase the total daily income, it is required to shift generations to the hours that high demand power values occurred. Wind Power Plants (WPP) have unstable and uncontrollable generation characteristic. For this reason, energy storage systems are needed to shift the generations of WPPs in time scale. In this study, four wind power plants (WPP) which are tied to the Turkish interconnected grid and a pumped hydro storage power plant (PSPP) that meets the energy storage requirement of these power plants are investigated in Turkey day ahead energy market. An optimization algorithm is developed using linear programming technique to maximize the day ahead market bids of these plants which are going to generate power together. When incomes and generations of the plants that are operated with optimization strategy is analyzed, it is seen that annual income increased by 2.737% compared with WPPs ‘s alone operation and generations are substantially shifted to the high demand power occurred hours.

Türkiye gün öncesi elektrik piyasasında rüzgar enerjisi ve pompaj depolamalı hidroelektrik santral için optimum teklif oluşturulması

Elektrik şebekesindeki talep güç arttığında enerji fiyatları artmakta, şebekedeki talep güç azaldığında enerji fiyatları azalmaktadır. Bu sebeple, günlük toplam gelirin arttırılması için üretimlerin yüksek talep güç değerlerinin oluştuğu saatlere kaydırılması gerekmektedir. Rüzgar Enerjisi Santralleri (RES) kararsız ve kontrol edilemeyen üretim karakteristiğine sahiptirler. Bu sebeple RES üretimlerini zaman ekseninde kaydırabilmek için enerji depolama sistemlerine ihtiyaç duyulmaktadır. Bu çalışmada; Türkiye enterkonnekte elektrik şebekesine bağlı dört adet Rüzgar Enerjisi Santrali (RES) ve bu santrallerin enerji depolama ihtiyacını karşılamak üzere düşünülmüş bir Pompaj Depolamalı Hidroelektrik Santral (PHES), Türkiye gün öncesi elektrik piyasasında incelenmiştir. Beraber enerji üretimi yapacak bu santrallerin gün öncesi piyasa tekliflerini optimize etmek üzere doğrusal programlama yöntemi kullanılarak bir optimizasyon algoritması geliştirilmiştir. Optimizasyon stratejisi ile işletilen santrallerin üretimleri ve gelirleri incelendiğinde, RES’lerin tek başına işletilmesi ile kıyasla senelik gelirin %2.737 oranında arttığı ve üretimlerin talep gücün yüksek olduğu saatlere büyük oranda kaydırılabildiği görülmüştür.
