Overview
The first self-compiled “15th Five-Year” new distribution-grid plan by the Guiyang power supply bureau of Southern Grid has passed review. It targets, by 2030, customer average outage time dropping below one hour, and aims for 100% coverage in three metrics: effective self-healing coverage, low-voltage transparency coverage, and “visible, measurable, adjustable, controllable” (the “four-can”) coverage for distributed PV. Reliability indicators for HV and MV networks will keep improving.
The plan deploys 34 key tasks across five dimensions, explicitly securing access for 763.1 MW of distributed new energy and 468,500 charging piles, and scaling up vehicle-to-grid (V2G) applications—aligned with source-grid-load-storage coordination and a new distribution-system build-out.
Background & Interpretation
1. Industry Background and Policy Context
As distributed PV, charging piles, storage, and flexible loads proliferate, the traditional radial grid is evolving into an active, bidirectional, intelligent distribution system. National policy keeps pushing high-quality distribution-grid development; Guiyang’s plan is a city-level sample of the new power system, upgrading from “having power” to “using power well and smartly.”
2. Core Drivers and Underlying Mechanism
The plan runs on five lines—infrastructure reinforcement, disaster resilience, source-grid-load-storage coordination, digital intelligence, and new-business exploration: aging-equipment renewal and dual-power upgrades boost supply; wind/ice/lightning/flood protections harden emergency response; smart patrol, self-healing, and flexible DC distribution land new tech; demos explore distributed smart grids, zero-carbon parks, and virtual power plants.
3. Market Structure and Industry Impact
Full “four-can” and self-healing coverage directly drives feeder automation, smart terminals, edge computing, and distributed dispatch software. The 763.1 MW distributed-energy and 468,500-pile targets open deterministic markets for inverters, chargers, storage, and EMS. New forms like VPPs and zero-carbon parks create aggregation and power-trading service opportunities.
Implications & Outlook
Near term, city-cluster grid upgrades enter a three-engine phase—reliability, transparency, interactivity. Watch distribution investment pace, distributed-resource access boundaries, V2G business-model maturity, and how market reform confirms distribution-side value.
Takeaways for Industry Participants
Equipment and software vendors should prioritize feeder automation, smart terminals, low-voltage transparency, and self-healing. New-energy and charging operators must pre-align with access and “four-can” compliance. Parks and consumers can join demand response and ancillary services via VPP and zero-carbon pilots, turning energy flexibility into revenue.
