Bypass Technique

The extensive use of fossil fuel is destroying the balance of nature that could lead to many problems in the forthcoming era. Renewable energy resources are a ray of hope to avoid possible destruction. Smart grid and distributed power generation systems are now mainly built with the help of renewable energy resources. The integration of renewable energy production system with the smart grid and distributed power generation is facing many challenges that include addressing the issue of isolation and power quality. This paper presents a new approach to address the aforementioned issues by proposing a hybrid bypass technique concept to improve the overall performance of the grid-tied inverter in solar power generation. The topology with the proposed technique is presented using traditional H5, oH5 and H6 inverter. Comparison of topologies with literature is carried out to check the feasibility of the method proposed. It is found that the leakage current of all the proposed inverters is 9 mA and total harmonic distortion is almost about 2%. The proposed topology has good efficiency, common mode and differential mode characteristics.

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.

Private Power

Electricity is the engine for the growth of economy of any country. Total installed electricity generation capacity of Pakistan is presently approx 20,000 MW as given in Table-1. Despite this, almost 40% of the population is without electricity. Pakistan has been blessed with tremendous resources for electrical power generation with hydel, coal, renewable energy resources and Nuclear power. Hydel, coal potential of more than 40,000 MW and 10,000 MW are available but only 15% of hydroelectric potential has been harnessed so for where as only 150 MW power plant on indigenous coal has been set up. To exploit Pakistan hydel and coal resources for power generation large investments are needed which Pakistan economy can not afford. Govt. of Pakistan has created an organization of private power and infrastructure board (PPIB) to facilitate private sector in the participation of power generator. PPIB is tapping the resources and facilitating the private sector for establishment of power projects. Pakistan is collaborating with China for establishment of Nuclear Power Plants and plan to generate up to 10,000 MW by year 2025. Renewable energy resources are also required to be tapped. This paper will focus on the Pakistan power generation potential by utilizing local resources keeping in view the next 20 year supply and demand position.

Pumped Storage

Renewable energy resources such as wind energy have a disadvantage that the quality of output power is lower than that of fossil fuel resources. To solve this problem, pumped storage power system with Archimedean screw is designed. The structure and principle of operation are introduced and the advantages and disadvantages are discussed according to the theory and the simulation. In this paper, comparison has been done by collecting and analyzing the data and simulated the system on different condition to show the differences of the two types of pumps working on the pumped storage system.

Renewable energy source (RES) enables us to diversify our energy supply. Renewable energy sources are getting more and more widespread, mainly due to the fact that they generate energy by keeping the environment clean. This increases our security of supply and improves European competitiveness creating new industries, jobs, economic growth and export opportunities, whilst also reducing our greenhouse gas emissions. This article proposes a simulation of a three-phase low voltage grid with power generation from photovoltaic sources. The proposed system consists of 192 photovoltaic (PV) panels distributed in 32 rows with each 12 PV panels.

Arranging and enhancement of small-scale lattices in determined zone examined in this paper miniaturized scale framework is associated with and without grid to meet the load profiles, particular micro grid arrangements with age from sustainable power sources are developed. Better examinations are then conveyed utilizing HOMER vitality programming to decide cost of economy, measuring, and locating and framework designs. Micro grid is likewise associated with the network because of shortage of supported sustainable power sources. This paper shows a short differentiate among the assorted cost types of gear, control the board and launches for every one of the setups. The improvement result shows the most reduced expense per unit and it allots the positioning for every framework.
