Over the last two decades, Pakistan’s energy demand has grown exponentially with very diminutive measures taken by the government to fulfill the needs. The large power plant projects are cumbersome, take years to be completed and require plenty of time to get fully operational. The idea of distributed generation works well in this case. Renewable energy comes well into play when we talk about distributed generation but the dependability of renewable energy resources on back-up such as batteries makes them unappealing. The objective of this paper is to practically implement a backup for the renewable energy resources using a mechanical storage such as CAES (Compressed Air Energy System). The proposed model is a composite technology, which comprises of EES (Electrical Energy Storage) and electrical power supply system. Solar energy driven compressor is used to compress the air in a storage tank, which is used on demand to drive the generator coupled air turbine. The fact that the developed system is solar powered, no other fuel is used with air and it uses mechanical storage instead of conventional storage like batteries, which makes the developed prototype system efficient, economical and durable as compared to the existing CAES. This paper focuses on the thermodynamic investigation, design and finally implementing a prototype CAES for a small load as an un-interrupted power supply system.

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.

The paper considers the problems of designing autonomous power supply systems using the renewable energy resources. The efficiency of using energy resources in conditions of growing prices for electricity brings significant saving of both energy and financial factors. The analyses show that the main losses of energy resources are the result of inefficient use, distribution and consumption of electrical energy. There has been stated one of the most important problems of energy saving: many existing consumers are located at a significant distance from centralized power supply systems. Today connecting such consumers to large power grids is economically inexpedient. These facilities are supplied from the stand-alone power plants. According to the program of energy saving and energy efficiency improvement of FGC UES, PJSC, reducing electricity consumption for auxiliary needs of transformer substations is one of the main mechanisms for the program implementation.

The power quality improvement becomes one of the important tasks while using microgrid as main power supply. Because the microgrid is combination of renewable energy resources. The renewable energy resources are intermittent in power supply and at the peak loading condition it has to supply the required power. So, the power quality problems may increase in that time. Out of all power quality issues the voltage drop and harmonic distortion is considered as the most serious one. In recent years unified power quality conditioner (UPQC) is emerged as most promising device which compensates both utility as well as customer side power quality disturbances in effective way. The compensating potentiality used in the UPQC is limited by the use of DC link voltage regulation and the conventional proportional integral (PI) controller. In this paper the compensating potentiality of the UPQC device is controlled by an adaptive neuro fuzzy inference system (ANFIS) control and it is powered from the available photovoltaics (PV) power generation. The effect of adding an intelligent UPQC is tested in the standard IEEE-14bus environment. MATLAB 2017b is used here for testing and plotting the simulation results.

Electrical power generation by means of renewable energy resources are more common now a days. In this method we used biomass energy to generate electrical power. We used a renewable energy resource of several reasons. Some of Reasons are increasing the usage of power, available resources are not satisfying the demand, urbanization. Biomass is a greenhouse gas. It does not cause any harmfull effects to the environment. On decomposing biomass we get electricity. The method we used is pyrolysis.

The objective of this project is to get power continuously from the renewable energy resources. Here the renewable energy resources utilized in this project are solar energy and rain water. Now-a-days using solar power for the generation of electricity has become extremely popular. Particularly within the agricultural fields the usage of solar panels for electricity increasing day by day. The flaw during this concept is whenever there's sun, there'll be solar power production Another project is based on the principle of using hybrid mechanism of mixing solar energy technology with piezo electrical power technology during this project, we'll have hybrid panel i.e., one side it'll have solar array and other side it'll have piezo electric plate.. So whenever the day is sunny, solar array are going to be faced up and whenever there's rainfall, the piezo electric plate are going to be faced up. For sensing the sun, we are using an LDR. solar power may be a very useful renewable source of energy, which can be the solution to the longer term for power, or energy needs, as heating seems to select up rapidly by installing Solar AND piezo electric generator for Street lights, it'll help to spice up the economy of INDIA. during this no need of manual operation like ON time and OFF time setting. By using this technique electricity consumption are often reduced which is one among the most advantage also. within the basic circuit of this technique we are using an LDR, solar array, piezo electric transducer, Battery, voltage booster, Transistor, , Resistor and an LED.

In India the requirement and availability of energy for power supply is 11,14408 million units and 10,90850 million units for 2015-16 and we also know that the human activities is mostly dependent on electrical power supply. The above fact clearly shows that the supply is not meeting the demand. As a result frequent power-cut is done and interrupted power supply is provided. The alternative for this problem is to switch towards renewable energy resources. Four different sources i.e. mains, generator, solar and inverter are used to provide uninterrupted power supply. Using the solar energy as one of the power source provides the solution for low energy resources since it is a non-renewable source of energy. The second objective of work is to provide automation which make the work faster, reliable, efficient, and reduce human efforts. Microcontroller (PIC/AT89C51) is used to provide automation in the switching between four different sources. The automation system used for switching requires separate source to provide an output signal which will operate the four different relays connected to sources respectively
