Renewable Energy Integration

SiC power electronics and solid-state transformers for PV and wind interconnection — higher efficiency, stricter grid-code compliance and DC coupling for hybrid plants.

Home/Applications/Renewable Energy

The Challenge

Every Megawatt of Renewable Power Has to Cross the Same Gate

Solar and wind are cheap to generate — but connecting them to the grid costs efficiency, and grid codes keep getting stricter.

Interconnection losses: Traditional plant transformers + inverters lose 3–5% of every megawatt hour
Stricter grid codes: LVRT/HVRT, reactive support and frequency response are now mandatory in most markets
Curtailment: Weak networks force operators to curtail generation when the grid cannot absorb it
Harmonics: Large inverter fleets inject harmonics that must be filtered to IEEE 519 / IEC 61000
Hybrid plants: PV + storage + wind on one connection needs flexible, bidirectional power conversion

Renewable Energy Power Converter and SST

Our Solution

Cleaner, Smarter Interconnection with SiC

From SiC-based power conversion stages to complete SST interconnection units — engineered around your plant, your grid code and your PPA economics.

High-Efficiency Conversion

SiC-based PCS and SST stages deliver ≥99% efficiency — more energy sold, less heat, better LCOE.

Grid-Code Compliance Built In

LVRT/HVRT, reactive power range and frequency response engineered to the specific grid code of your market.

DC Coupling for Hybrid Plants

PV and storage share one DC bus through a common SST interconnection — fewer stages, lower cost, higher round-trip efficiency.

Harmonic & PQ Management

Active filtering and reactive compensation integrated into the interconnection unit — no separate filter banks.

Fast Dynamic Response

Millisecond-level control keeps the plant stable through irradiance and wind swings — and earns ancillary-service revenue.

Compact Plant Footprint

High-frequency magnetics shrink the interconnection station — more land for generation, less for equipment.

FAQ

Common Questions

Is SST interconnection economically competitive today?

For most plain PV or wind plants, conventional transformer + PCS remains the economical default. SST interconnection wins where grid codes demand advanced support, where space is constrained, or where hybrid DC coupling (PV + storage) removes a conversion stage — we help you model both options honestly.

Which grid codes do you design against?

We engineer against the grid code of your market — IEEE 1547 (US), EN 50549 / VDE-AR-N 4110 (Europe), and national codes on request. The compliance matrix is part of the technical proposal.

Can you retrofit an existing plant's interconnection?

Yes. Adding SiC-based PQ equipment or replacing the interconnection stage of an existing plant is a common upgrade path to meet new grid codes or increase capacity without new land.
