Energy is the basic requirement for the development of a country. Pakistan is fronting meaningful contests in the sector of energy on the way to conference the demand which is significantly increasing annually. The government of Pakistan have initiated various renewable energy projects for the provision of electrical energy particularly to the rural areas where population is less, and extension of main grid-system is not fiscally and technically practicable due to huge rate asset essential for transmission network. In electrical power system the users need uninterrupted power supply at rated frequency and voltage. Due to existence of different kinds of loads having different structure and load demand the frequency and voltage of micro hydro plant (MHP) may not be continuous. To keep these constraints in the specified boundaries appropriate control approach must be recognized for the system. Frequency is maintained by eliminating the difference among generation and load demand through Electronic load controller (ELC). ELC function is to dump extra power into dummy loads, when consumers switch their loads off, maintaining system frequency constant. The purpose of this research paper is to analyses the connected MHP ELCs in KPK via considering the case study of Ashran Valley District Swat and Tehsildar kali district Mardan to know the impacts of voltage, frequency and power factor of these MHP ELCs likewise to recommend for improvement. Comprehensive literature review was carried out to achieve these goals. The real time data was collected using the site observation, and the analyses of real time data (voltage, frequency and power factor) of MHPs ELCs are analyzed through Microsoft Excel software. This research work concludes that these MHPPs requires proper management, quality work and skillful operators to have a sustainable and reliable system for the community.
