Economic Analysis of Demand Side Management with Residential PV System and Energy Storage System

Öz

Renewable energy sources (RESs) as distributed generation (DG) have an important place on distribution networks (DNs) in recent years. RESs are being used for voltage stability, low power losses and low energy cost. Two way energy transmission is possible after the development of smart distribution girds and different electricity tariffs can be applied for customers at different times of day. PV modules are growing rapidly for residential applications and PV modules applications are becoming widespread together with technological improvements. Because of the raw material continuity problem of PV modules, energy storage systems (ESSs) can be used at residential PV applications. In this paper, economical effect of the residential PV system for customer is investigated and ESS is used with PV system for more efficient PV usage. The charge/discharge timing of ESS has been set to obtain a minimum electricity bill for one home. Then we used distribution network to analyse the impact of the residential PV application. For this purpose, it was accepted that 25 per cent of homes at distribution network have residential PV and ESS (RPVESS).

Dağıtık üretim olarak yenilenebilir enerji kaynakları, son yıllarda dağıtım şebekelerinde önemli bir yere sahiptir. Yenilenebilir enerji kaynakları; gerilim kararlılığı, düşük güç kaybı ve düşük enerji maliyeti için kullanılmaya başlanmıştır. Akıllı dağıtım şebekelerinin geliştirilmesinden sonra iki yönlü enerji aktarımı ve müşteriler için günün farklı saatlerinde farklı elektrik tarifeleri uygulanabilir hale gelmiştir. PV modüller konut uygulamaları için hızla büyümekte ve PV modül uygulamaları teknolojik gelişmelerle birlikte yaygınlaşmaktadır. PV modüllerin hammadde sürekliliği sorunu nedeniyle, konut PV uygulamalarında enerji depolama sistemleri kullanılabilir. Bu çalışmada, müşteriler için konut PV sisteminin ekonomik etkisi araştırılmış ve daha etkin PV kullanımı için PV sistemi ile birlikte enerji depolama sistemi kullanılmıştır. Enerji depolama sisteminin şarj / deşarj zamanlaması, bir ev için elektrik faturası minimum olarak ayarlanacak şekilde belirlenmiştir. Daha sonra konut PV uygulamasının etkisini analiz etmek için dağıtım şebekesi kullanılmıştır. Bu amaçla, dağıtım şebekesindeki evlerin yüzde 25'inin konut PV ve Enerji Depolama Sistemi’ne (RPVESS) sahip olduğu kabul edilmiştir.
