Most of the industries including the oil sector are looking forward towards the renewable energy resources with proper energy management system (EMS) as it is the need of time. For this purpose, solar and wind energy are the renewable energy resources, which are obtained from natural resources and produce clean and environment -friendly electrical energy and can be used for oil depots. The proper utilization of solar and wind energy from natural resource may result in economical and cost-effective EMS. In the proposed research work, an effective energy management demonstration is delivered to ensure the ceaseless flexibility of power. Furthermore, reduction of production per unit cost to the oil sector industry by utilizing multiple objectives streamlining. In the proposed oil depot, connected loads are divided into Shiftable and Non-Shiftable loads and then apply Branch and Bound Algorithm (BnB) with binary integer linear programming (BILP). By using the BnB technique, selected shiftable loads are shifted to the low cost energy resource automatically and resultantly, we get the low price unit cost and continuous power supply. Simulation results for the above-mentioned research work are performed on MATLAB. The proposed technique helps to reduce the power stack shedding issue as well.

This paper addressed assessing feasibility of hybrid use of ocean renewable energy, such as wave and wind energy around Japanese coast. At first, wave and wind energy theoretical potentials were calculated and, in the second step, correlation coefficient between wave and wind energy was computed around Japanese coast. Sea area suitable for hybrid use of ocean renewable energy resources is supposed to have high potential for some types of energy resources. Furthermore, correlation of power generation between wave and wind energy resources should be low because one energy resource needs to complement another one for stabilizing power generation. Based on the assumptions, feasibility of wind and wave energy was evaluated on some sea areas where R&D project are ongoing.

Advantages And Disadvantages

The non-renewable energy resources are limited and depleting gradually. As such, energy security has attained the greatest amount of attention globally than ever before. In the meantime, energy crises are already affecting the developing countries such as Pakistan, even though one-third of the population of the country is not even not connected to the national electricity grid. The population with access to on-grid electricity is enduring load shedding of more than 12 h a day. This situation is alarming and require immediate attention is required so as to add alternative energy resources to the country, which has long been relying on imported fuels. It is, therefore, high time that the abundant potential in the renewable energy resources of Pakistan such as solar, wind, and biomass are harnessed. These renewable energy resources are economical and environmentally friendly, and thus considered as sustainable, and the utilization of these in meeting energy demands can help to conserve conventional resources early diminishing. This paper provides a detailed description of the energy consumption and load-shedding scenario in Pakistan thereby focusing specifically Sindh and Baluchistan provinces. Since, wind energy is considered one of the cost-effective renewable resources, six potential sites in these two provinces are considered in this study. These sites lie within 250 km of the southeastern and 800 km of the southwestern regions of Pakistan. One-year wind speed data have been reported for variable heights of these proposed sites which represent to have an annual average wind speed of 6.63 m/s and 5.33 m/s respectively. The power generation data for these location of two provinces is 7.653 GWh, and 5.456 GWh per annum respectively. This study also elaborates on the advantages and disadvantages of harvesting and installing the wind energy and provides a technical proposal for the generation of electricity from the wind in the selected remote zones which are off the national grid. The findings of this paper will help concerned government departments to devise appropriate policies and attract investment in the wind energy sector to eradicate the on-going electricity crisis.

The natural resources which can be renewed are Renewable energy resources. Due to the increased load demand in recent years demand for renewable energy resources have been increasing and attracting us. If this can be met using the renewable energy resources then it can be harmless to the environment. We opt Wind energy because of its enormous advantages, wind energy has emerged as the most reliable source of electric power, and is economically viable with the conventional sources. Wind energy is one of the most available forms of renewable energy. Loads can be classified based on their distance from the main grid. These can be remote villages, islands, ships, forests, deserts etc. For such loads there should be precise electrification system called as standalone generator system which provides constant nominal voltage and frequency. The Wind Energy Conversion system unit features a wind-turbine-driven Synchronous Generator, a diode bridge rectifier, a boost dc/dc converter, a battery bank, and a PWM dc/ac inverter. In this paper, distribution Generation is based on WECS using Synchronous Generator anticipated with a battery and Rectifier. The topology for the same has been demonstrated using MATLAB Simulink based simulations.

Currently, many countries try to satisfy their energy needs with an increasing usage of renewable resources. The general motivations, with varying weighting in the different countries, are ecological reasons, concerns about energy security, and economical considerations. A for now rather theoretical question, although interesting for opening a long-term perspective, is how an energy supply from exclusively renewable energy resources could look like. This question has to be answered individually for any specific energy supply system. The present paper has the objective to present and evaluate a scenario for an electricity supply only from renewable energy resources for the Java-Bali grid. After designing a load time series for the year 2050 for the Java-Bali grid, a scenario is developed how to cover the load with electricity from renewable energy resources alone. Assumptions about the usable energy sources are made as well as assumptions about the available power plant capacity or energy potential. A specific challenge is the fact that solar energy must be the main source in such a renewable-energy based system, which comes with the need for a large storage capacity to match the power supply at any time with the load. Several possibilities are presented how to bring down the storage capacity: the increment of the installed PV capacity, the usage of bioenergy for seasonal balancing, and the complementation of the proposed short-term storage with an additional long-term storage. The study shows some of the specific challenges that a gradual transformation of the current electricity supply system on Java and Bali into a renewable-energy-based one would face and gives some hints about how to cope with these challenges. Scenarios like the one designed in this study are an important tool for decision-makers who face the task to scrutinize the consequences of choosing between different development paths. Article History: Received: August 15th 2017; Received: October 18th 2017; Accepted: January 14th 2018; Available onlineHow to Cite This Article: Günther, M., Ganal, I. and Bofinger, S.

Intervention Technique

Solar photovoltaic and wind energy resources are gaining more popularity as an integrated or complementary power system. Integrating or complementing either solar photovoltaic or wind energy would be an ideal to reduce the intermittency when self-intervention from either one of the input resources is performed. The self-intervention plays a vital role in renewable energy resources hybridization, hence this paper proposes to model and simulate an adaptive voltage-divider sensing method to perform the self-intervention technique for renewable energy resources hybridization using the Stateflow/Simulink MATLAB software. The proposed adaptive voltage-divider sensing method performs the voltage sensing and measurement for input voltages from either one of the renewable energy resources adopted. This voltage sensing and measurement is an important factor to demonstrate the self-intervention in the designed and developed Stateflow/Simulink MATLAB Controller. The proposed adaptive voltage-divider sensing method and self-intervention technique for renewable energy resources hybridization is analyzed along with the voltage sensing and measurement at the inputs. The self-intervention state modes for the inputs from the renewable energy resources hybridization are given by the simulation results in this study.

Most of existing power grids are designed neither by latest technologies nor to comply with quickly climate changes, the new intelligent power grids are urgently needed and will soon be applied to the power markets. In the smart grid, the large-scale renewable energy contribution tends to expand vastly. This paper is focusing on the wind energy. Wind’s inherent intermittency and unpredictability make its increased penetration into the power system grids an area requiring significant analysis and research. Notwithstanding, because of the changeable nature of the wind energy, this may lead to a high oscillation on the power system frequency. From another aspect, A lot of scientific research is searching for smart solutions and tools to support and enhance the integration of the renewable energy resources into the electrical grids without additional costs for the power system, so the world scientific research is directed to exploit the plugin hybrid electric vehicles (PHEVs) which are considered as the sustainable and environmental friendly transportation system in the next period around the world. PHEVs are considered as the scattered batteries, which will enhance the integrating of the renewable energy resources into the electrical power system. In this paper, the performance of two-area interconnected power system with high wind energy penetration is analyzed in the presence of the plug-in hybrid electric vehicles when using Ziegler and Nicholas method (Nguyen & Mitra, 2018).
