¶ What This Documentation Covers & Why
This wiki is the single source of truth for TSPI’s energy automation stack: PPC (plant power control), EMS, and the TSPI API. It’s designed for operators, engineers, admins, integrators, and traders working across solar, wind, BESS, and hybrid sites.
¶ Purpose
- Clarity: Define how TSPI products fit together to keep plants grid-compliant and stable (PPC) and observable/controllable (EMS).
- Speed: Provide role-based guides you can follow during operations, commissioning, and troubleshooting.
- Consistency: Standardize setup, networking, security, and comms for repeatable deployments.
- Integration: Document how to connect external SCADA/trading systems through the TSPI API.
¶ What You’ll Find Here
- PPC Concepts: Control loops (active/reactive power, voltage/frequency), setpoint strategies, plant coordination, grid-code features.
- PPC GUIs: Role-based guides (User vs. Admin/Engineering) for both MINI and MAXI, incl. commissioning and advanced settings.
- EMS: SCADA navigation, alarms, historian, reports, Nord Pool export limiting, remote plant control.
- Networking & Security: Topologies, device roles, protocols, users/roles, VPN/TLS considerations.
- API: Endpoints for telemetry, setpoints, alarms/events, asset metadata, and integration workflows.
TSPI focuses on advanced energy automation and grid compliance for C&I and utility-scale projects, delivering PPC, EMS, and testing/automation expertise.

TSPI integrates solar, wind, and BESS into hybrid plants. Plant complexity is standardized into A–D categories so sizing, control, and commissioning expectations are clear:
Controller selection: TSPI deploys PPC MINI for A–C plants (up to 15 MW), and PPC MAXI for D utility-scale sites (15 MW+).
¶ Architecture at a Glance
- Assets: Inverters, BESS PCS/BMS, weather stations, meters, breakers/IEDs, grid interconnect (POI).
- Plant Control: Active/reactive power regulation, voltage, frequency response, PF control, ramp-rate & export limiting.
- Communications: Modbus/TCP, OPC-UA and utility/market-facing links via EMS, TSPInsight, TSPI API.
- Setpoint Flow: Trader/EMS → PPC (POI-referenced commands) → Asset controllers (inverters/BESS) with feedback and alarms.
- Reliability: Redundant metering/sensors at POI, watchdogs/fail-safes, alarm policies, safe fallback strategies.
¶ PPC — Plant Power Controller
TSPI’s PPC stabilizes plant behavior at the Point of Interconnection (POI). It regulates active/reactive power, supports voltage/frequency objectives, coordinates multiple assets (inverters, BESS, wind), and integrates with EMS for real-time visibility and control. It is built to help sites meet TSO/DSO grid-code requirements while maximizing production and minimizing curtailment.
¶ PPC MINI (up to 15 MW)
PPC MINI is a compact controller tailored for 100 kW–15 MW sites. It simplifies deployment while ensuring
grid compliance and stable export: POI-based active/reactive control, PF/Volt-Var, and smooth ramping. It includes a dedicated GUI
for daily operations and configuration, with role-based access.

¶ PPC MAXI (≥15 MW)
PPC MAXI targets utility-scale sites that require advanced grid support (e.g., synthetic inertia, POD),
fine-grained setpoint control, and coordination of many inverters/BESS blocks. It comes with a full-featured GUI for both operators
and engineers to manage control modes, limits, alarms, and tuning.

¶ EMS — TSPInsight
TSPInsight provides end-to-end plant visibility and remote control: real-time dashboards, alarm & event management, historian and reporting, plus interactive commands for power limiting (incl. Nord Pool constraints), I/O control, and automation.
¶ Key Capabilities
- Unified Monitoring: Solar, wind, and BESS on one platform with role-based access and fleet overviews.
- Advanced Control & Modeling: Works in tandem with PPC; supports fast responses (<100 ms class) and power-factor optimization.
- Security: TLS, VPN, encrypted communications; available as local, cloud, or hybrid deployments.
- Analytics: Alarms, historical trends, KPIs, and reporting for performance and compliance.
¶ TSPInsight
Streamlined SCADA for plant monitoring: essential dashboards, multi-asset control views, advanced alarm logic, plant-level
automations, and fleet analytics for large parks.
