Optimal cable sizing in PV systems: case study

It is often beneficial to over-size the cross-section of electricity cables compared to the standard values that follow out of voltage and current calculations. In the large majority of cases, oversizing has a positive influence on the Life Cycle Cost of the installation. The investment in larger cable is easily paid back by the reduction of Joule losses inside the cable and the subsequent savings on electricity bills.

Learning from Actual Dual-Wiring Installation - Easy Case & Difficult Case

Dual-wiring installations have been conducted after the confirmation of its effectiveness through the field tests.  There were several findings from actual installation, which could be shared as valuable insights that can be gained only through the actual installation.  From the findings we can now recommend the most effective way of energy saving and peak-demand control by Dual-wiring.

Impact of Regulation on the Annual Account and Balance Sheet for a Theoretical Utility

The purpose of this model is to help understand how the interaction between regulatory policies and the subsequent response of a Distribution System Operator (DSO) impact the DSOs financial performance. In particular, the model can be used to explore the interactions between regulatory decisions regarding tariff setting and quality penalty schemes, and DSO decisions with regards to cost control, investment levels and the resulting network quality performance.

All hope relies on electrical energy storage

The development of Electrical Energy Storage technology (EES) carries the weight of huge expectations. According to an earlier International Electrotechnical Commission White Paper, many of the medium and long-term renewable energy targets that have been set by governments are impossible to achieve without a fundamental breakthrough in storage technology. Energy storage systems already exist, but a major technology shift is required to enable large-scale deployment.

8.6.3 The Smart Starter by Philips

In 2012 Philips released their third novelty in this area, this time only a starter, the so-called Smart Starter, that was meant for use with any commonplace T8 fluorescent lamp between 32 W and 58 W and a magnetic ballast. It is an electronic starter, but programmed to a certain time interval, by default 8am to 6pm on weekdays.

Expert experiences show that in industrial plants about 10% or more of the equipment is uninsulated or covered with damaged insulation. Furthermore, the level of insulation applied is typically based on a minimum investment decision following requirements regarding the maximum surface temperature to avoid personal injuries, minimum process needs or based on generic maximum heat loss rates only.

Photovoltaic Grid Parity – Webinar Series

PV Grid Parity is defined as the moment when PV Levelized Cost of Energy becomes competitive with retail electricity prices, assuming that 100% of the electricity is self-consumed instantaneously. This point has already been reached in many regions of the world.
