Electricity is an important component of our life. It plays an important role in social development as it improves people's living standards in urban as well as in rural areas of Pakistan. According to the International Energy Agency (IEA), till 2017, 45% of Pakistani were living without electricity in rural areas. In Pakistan, load shedding remains a critical issue due to hectic energy threats, which are alarming for development especially in rural areas. Currently, there are 10 hours of load shading in cities and 12 to 14 hours in rural areas. There is a need to implement innovative, less costly tools and materials that can convert fossil fuels into renewable energy resources to generate electricity to overcome the load shedding problems in Pakistan, especially in rural areas. To overcome the load-shedding problems and to convert the fossil fuels into renewable energy successfully, we have proposed a Rural Areas Interoperability (RAI) framework for analyzing the geographical and environmental situations, feudal system in Sindh, Balochistan, KPK and some areas in Punjab. Moreover, we have suggested a suitable renewable energy resource out of existing renewable energy resources i.e. solar system, wind energy, hydro energy, biomass biogas and thermal energy in a particular area to generate the electricity after analyzing the security issues for installation of these renewable energy resources in the specific area of a district in Pakistan.

“…Decentralized generation occurs when electricity is produced and transmitted using small-scale technology closer to the end users. These distributed generation systems, while not limited to, are primarily based on renewable technology such as wind turbines, photovoltaic cells, geothermal electricity, and micro hydropower plants [3][4]. A grid-tie inverter (GTI) is a type of power converter that converts direct current (DC) to alternating current (AC) and works in tandem with a power grid, typically at 120 Vrms at 60 Hz or 240 Vrms at 50 Hz.…”

The majority of companies are shifting to renewable energy sources as non-renewable fuels are increasingly depleting. Solar energy is a dependable form of green energy. The solar energy after converting to AC through an inverter it is possible to inject into the grid to support distributed power generation system. Transformerless grid-tied inverters have become popular due to their lightweight and reduced cost. The leakage current does exist in this kind of inverter that deteriorate the performance of the inverter. This paper presents a novel H5-ZVR, H5-ZVRD and H5-ZVRS topologies to address the leakage current issue. These inverters take the benefit of hybrid technology, where H5 inverters are integrated with HB-ZVR topologies. To operate the inverter at its highest performance an appropriate hybrid pulse width modulation is also presented. The inverters are simulated in MATLAB to verify the operation and it is found that the leakage current of the inverters is considerably reduced as compared to HB-ZVR topologies. The leakage current of H5-ZVR, H5-ZVRD and H5-ZVRS are found to be 10 mA, 7.3 mA and 7.3 mA respectively and THD of these modules are 1.03%, 0.91% and 0.91% respectively. Also, the topologies present good common mode and differential mode characteristics.

“…To mitigate the effect of harmonics on the grid while maintaining stable voltage profile, passive/active, or hybrid filters have been utilized. Passive filters are cheap and easy option to install, but they are bulky and prone to resonance problems [5] [6]. Active filters (AF) have complicated design compared to passive ones.…”

In this paper, a novel dual-function grid-connected solar inverter is developed for better utility interaction applications. The proposed topology is able to inject active power, reactive power, and mitigate harmonic problems caused by non-linear loads. The proposed configuration consists of switched LC-connected inverter (SLC-CI) in parallel with static VAR compensator (SVC) to achieve the design requirements. The system description, mathematical model, control algorithm, and parameter design of the proposed system is systematically developed to ensure acceptable performance. The system performance is evaluated with both linear and non-linear loads and compared to two conventional topologies; inductive and capacitive grid connected inverters. The results demonstrate that the proposed topology have better performance, comparing to other topologies, in terms of using lower DC-bus voltage (25% less) and using around half the power rating of inverter. Moreover, the proposed double switched LC filter-connected inverter (DSLC-CI) shows its ability to work as active power filter and mitigate harmonics to acceptable level.
