Energy Demands

To a great extent, Pakistan and Turkey rely on imported fossil fuels to meet their energy demands. Pakistan is moving in the right direction, placing focus on renewable energy resources in its current infrastructure in order to address the energy shortage. Several projects (e.g., wind power and solar PV (photovoltaic) technologies) are operational or under development; they are intended to reduce energy challenges in Pakistan. The new government in Pakistan aims to increase the share of renewable energy in total power generation to 30% by 2030. On the other hand, Turkey surpasses Pakistan in renewable energy resources; for example, there are 186 operational wind energy power plants across the country. In addition, Turkey utilizes solar energy—mainly for residential usage. Turkey’s Vision 2023 energy agenda aims to supply 30% of their power demands from modern renewable energy resources. Turkey has implemented solar PV, solar buildings, wind power plants, geothermal energy resources, and biomass technology for heating, cooling and electricity generation. At present, Turkey’s supply to meet energy demands in the country is 56% fossil fuel energy resources and 44% renewable energy, including hydropower. Accessible details reveal that geothermal energy resources have been continuously neglected in Pakistan by the Ministry of Energy (power division); this is in contrast to the Turkish case, in which utilization of geothermal energy resources for heating and cooling purposes is efficient. With all the facts and figures under consideration, in this paper, comparative analyses are performed which reveal that the production of electricity from geothermal energy technologies is lower than the massive potential in both countries. Recommendations are made for important policies to promote renewable energy technologies, which could effectively support energy decentralization by providing electricity to rural areas and the national grid.

Renewable Energy Development

Abstract Background The global commitment to climate change mitigation enforces the worldwide development of renewable energy sources. Therefore, various studies have investigated the growth of renewable energy in Malaysia, most commonly based on biogas and hydropower. In this article, the dynamics of Malaysia’s renewable energy development is critically examined by using the latest official national reports and other reliable resources. Results The study reveals the influencing factors that shape renewable energy growth in a developing country endowed with substantial biomass resources, such as Malaysia. Likewise, it evaluates the evolution of renewable energy in the electricity sector. In 2017, renewable energy represented about 3.5% of the Malaysian electricity generation mix with 1122 MW of installed capacity. A closer look into the renewable energy resources, i.e. biomass, biogas, solar and small hydro power, revealed that over 47% of the grid-connected power generation came from solar photovoltaic (PV) energy. While solar PV capacity continues to accelerate, the development of other renewable resources, especially biomass, is seeing growth at a significantly slower pace. This article investigates the underlying causes of the skewed development rate as well as the potential strategies that may be adopted to promote a diversification of renewable energy resources. In light of this, introduction of a new national bioenergy policy is proposed, through which four essential programmes could be implemented: (i) enhanced bioenergy conversion efficiency and waste management, (ii) biomass co-firing in coal power plants, (iii) conversion of biogas to biomethane and bio-compressed natural gas (bio-CNG), (iv) large-scale biomass power plants. A total of 4487 MW of additional power could be connected to the grid upon successful implementation of a large-scale biomass power plant programme. Conclusions The establishment of a comprehensive and inclusive national bioenergy policy will lead towards a sustainable future of renewable energy development in Malaysia.

Objectives : The world is getting more polluted day by day and living conditions are getting harder and harder. The Covid 19 process explains this situation even better. Global warming will show its effect more heavily if measures are not taken. There is a close relationship between global warming and the type and method of energy used. The use of fossil fuels by people pollutes the environment too much, and the use of alternative energy sources is gaining importance instead. Here, the issue of use and management of renewable energy sources comes to the fore. Turkey is a country with rich renewable energy resources and experience in cooperatives. In this study, it is aimed to reveal the current situation and problems of renewable energy cooperatives, which can be a model for managing Turkey’s renewable energy resources.Methods : In the study, a literature review method was used by examining domestic and foreign resources related to renewable energy and renewable energy cooperatives. Some of the data obtained were arranged in tables and used in the study.Results and Discussion : It is very important for Turkey to develop renewable energy resources and increase the share of renewable energy resources among other resources. Because Turkey is a developing country and its population is increasing day by day. It is essential to use renewable energy for the energy need of the increasing population and the least environmental pollution. Within the scope of 2023 targets in Turkey, it is planned to produce 34 thousand MW of hydroelectric, 20 thousand MW of wind energy, solar energy, 5 thousand MW, 1,000 MW of geothermal energy and 1,000 MW of geothermal energy and biomass energy. In order to achieve this goal, it is planned to invest approximately 60 billion dollars in renewable energy sources. Cooperatives are one of the most effective ways in which Turkey can use its renewable energy resources. Because cooperative is a method known to the Turkish society and it would be beneficial to transfer it to the renewable energy field.Conclusion : Turkey is a developing country and its energy needs are increasing day by day. It is very important to use the renewable energy resources it has correctly and in a planned way. In this respect, it should be understood that renewable energy cooperatives are quite compatible with Turkey. Turkey should provide the necessary legal and administrative structure for the development of renewable energy cooperatives and develop it with financial support in order to make its increasing energy needs sustainable.

Over the last decades, the energy market around the world has reshaped due to accommodating the high penetration of renewable energy resources. Although renewable energy sources have brought various benefits, including low operation cost of wind and solar PV power plants, and reducing the environmental risks associated with the conventional power resources, they have imposed a wide range of difficulties in power system planning and operation. Naturally, classical optimal power flow (OPF) is a nonlinear problem. Integrating renewable energy resources with conventional thermal power generators escalates the difficulty of the OPF problem due to the uncertain and intermittent nature of these resources. To address the complexity associated with the process of the integration of renewable energy resources into the classical electric power systems, two probability distribution functions (Weibull and lognormal) are used to forecast the voltaic power output of wind and solar photovoltaic, respectively. Optimal power flow, including renewable energy, is formulated as a single-objective and multi-objective problem in which many objective functions are considered, such as minimizing the fuel cost, emission, real power loss, and voltage deviation. Real power generation, bus voltage, load tap changers ratios, and shunt compensators values are optimized under various power systems’ constraints. This paper aims to solve the OPF problem and examines the effect of renewable energy resources on the above-mentioned objective functions. A combined model of wind integrated IEEE 30-bus system, solar PV integrated IEEE 30-bus system, and hybrid wind and solar PV integrated IEEE 30-bus system are performed using the equilibrium optimizer technique (EO) and other five heuristic search methods. A comparison of simulation and statistical results of EO with other optimization techniques showed that EO is more effective and superior.

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.
