Power System Studies & Analysis Service Provider in Malaysia
Helping You Make Smart Decisions About Your Power System
As the energy landscape rapidly evolves, integrating renewable energy and distributed energy resources presents new technical challenges for utilities, developers, and industrial players alike. From shifting grid codes to complex interconnection demands, every decision around your power system must be precise, informed, and future-proof.
At VELLD, we specialise in delivering comprehensive Power System Studies & Analysis tailored for modern energy infrastructure. Backed by years of hands-on experience, certified expertise, and advanced simulation tools, we help clients assess feasibility, ensure grid compliance, and make confident, data-driven decisions at every stage of their project.
Clients We Work With
Industrial Facilities
From manufacturing plants to heavy processing industries, we conduct studies on waste heat recovery systems, CCGTs, and grid-connected solar PV setups to enhance energy efficiency, meet production demands, and reduce operating costs—all while maintaining grid reliability and safety compliance.
Commercial Enterprises
For office buildings, malls, and commercial complexes, our focus is on power factor correction, load flow analysis, and self-consumption rooftop solar studies that reduce energy bills, support green certifications, and ensure electrical systems meet regulatory expectations.
Utility Companies
Our team supports utilities with grid impact studies, dynamic simulations, and reactive power analysis for the integration of CCGT, renewable energy plants, and distributed energy resources. We help utilities meet technical and regulatory requirements while maintaining system stability.
Energy Developers
We partner with solar, hydro, and biomass project developers across Asia to deliver preliminary feasibility assessments, interconnection studies, and simulation model validation for large-scale renewable energy projects, ensuring a smooth path from design to connection.
Our Specialised Study Capabilities
We deliver end-to-end studies to support every stage of your project, including:
Transmission Power System Studies
Including Steady State Analysis (Load flow and contingency analysis, short circuit analysis and reactive power requirement and Power Factor Correction) and Dynamic Studies (including Transient Stability Analysis, Frequency Response, Fault Ride Through and Power Quality Analysis) to meet Grid Code Compliance.
Simulation Model Validation/Machine Model Validation (SMV)
Validation of the developed network and generator/inverter/Battery Energy Storage System (BESS) models to ensure alignment with actual plant performance.
Connection Assessment Studies (CAS)
Required under self-consumption schemes such as SELCO, assessing system readiness for grid interconnection.
Preliminary Power System Studies
Early stage analysis to estimate the plant potential injection capacity at the proposed location.
