Correlation between Weather Variables and Electricity Demand

Abstract In the industrial era 4.0 as it is today, along with the increasing need for electrical energy, energy efficiency is an essential factor in achieving energy production cost efficiency. Efficiency will be achieved if electricity production can be adjusted to the customer’s electrical load. However, adjusting the electricity production poses a challenge, namely the difficulty of predicting the daily electricity load of customers. There are many factors that affect the electric load. One of the main factors is the weather. Therefore, this study focuses on the correlation of weather parameters on load demand. The weather parameters consist of temperature, rainfall, solar radiation, and wind speed. Case studies were conducted in Bali Island and Central Java Province. This paper looked for correlations between weather parameters with the load demand, especially in the island of Bali and Central Java Province.

Abstract — The growth of electricity load in Ngawi and Magetan areas has increased due to the government's plan to build several infrastructure and industrial areas. The electricity provider must be able to predict the system's ability to serve consumers. The planning for the construction of substations (GI) is carried out to ensure that all electricity loads served can be properly accommodated. This research uses historical data in predicting the amount of electricity demand in the Mantingan substation area from 2019 to 2026. The method used is a linear regression with one-stage planning, which is for 8 years (long term). The results recommend that the current operating system requires an electric load by moving three feeders in Magetan substation and Ngawi substation to Mantingan substation. The three feeders, namely the Walikukun and Trinil feeders, were sourced from the Ngawi substation and the Sine feeders which were sourced from the Magetan substation. The prospective areas for the construction of the Mantingan Substation are Widodaren, Mantingan, Karanganyar, Ngrambe, and Sine areas. Research shows that a newly built substation with a capacity of 60 MVA and the load value of the Mantingan substation transformer for 8 years has an average of 41.41% and an average of biaya pokok penyedia listrik (BPP) of Rp. 2,101. Keywords— transformer capacity, electrical energy consumption, linear regression.

Wave energy resource assessment is crucial for the development of the marine renewable industry. High-frequency radars (HF radars) have been demonstrated to be a useful wave measuring tool. Therefore, in this work, we evaluated the accuracy of two CODAR Seasonde HF radars for describing the wave energy resource of two offshore areas in the west Galician coast, Spain (Vilán and Silleiro capes). The resulting wave characterization was used to estimate the electricity production of two wave energy converters. Results were validated against wave data from two buoys and two numerical models (SIMAR, (Marine Simulation) and WaveWatch III). The statistical validation revealed that the radar of Silleiro cape significantly overestimates the wave power, mainly due to a large overestimation of the wave energy period. The effect of the radars’ data loss during low wave energy periods on the mean wave energy is partially compensated with the overestimation of wave height and energy period. The theoretical electrical energy production of the wave energy converters was also affected by these differences. Energy period estimation was found to be highly conditioned to the unimodal interpretation of the wave spectrum, and it is expected that new releases of the radar software will be able to characterize different sea states independently.

Current Energy

Generating electricity through renewable energies is growing increasingly to reduce the huge demand on electricity and the impact of fossil energies on the environment, the most common sources forms used are: the wind, the sun, the photovoltaic and the thermal, without forgetting hydropower by the bays of dams. Fortunately, 70% of our planet is covered by the seas and oceans, this area constitutes a huge potential for electricity production to be exploited. The scientific advances of recent years allow a better exploitation of these resources especially the marine current due to its reliability and predictability. The marine current energy is extracted using a hydrokinetic turbine (HKT) which transform the kinetic energy of water into an electrical energy. The exploitation of this resource needs in the first step the assessment of marine currents in the study area for implementing the HKT, and the second step is designing an adequate technology. The main goal of this study is the assessment of the marine current resource on the Moroccan Mediterranean coast to evaluate the suitable area to implement the HKT, and to determine the marine current speed intensities at different depths. As well as, to estimate an average potential existing in the site. Moreover, we will conduct a study based on the results of the assessment that was made to design a horizontal axis marine current turbine (HAMCT). Two hydrofoil profile were considered to design a HAMCT using the Blade Element Theory (BEM) and calculating their performances adapted to the site conditions Naca4415 and s8052. In addition, a comparison was made between this two HAMCT hydrofoil profile for deciding the best one for implementing in the studied area.
