Energy Management Strategies Using Schneider Electric Tools

Schneider Electric’s integrated energy management solutions leverage advanced software, automation, and real-time analytics to optimize building performance, reduce operational costs, and enhance sustainability. By combining tools like Power Monitoring Expert (PME), AVEVA System Platform, and StruxureWare, organizations can achieve measurable improvements in energy efficiency, demand response compliance, and infrastructure resilience. These strategies are particularly impactful in high-consumption environments such as commercial buildings, industrial facilities, and data centers, where energy waste and peak demand challenges are critical.

The following sections detail how Schneider Electric’s tools address energy waste identification, demand response automation, and cost reduction in data centers, supported by actionable methodologies and a case study of a mid-sized office building retrofit.


Identifying Energy Waste with Power Monitoring Expert (PME) for Peak Demand Reduction and Load Balancing

Power Monitoring Expert (PME) is a cloud-based energy management platform that provides real-time visibility into electrical consumption across buildings, enabling proactive identification of inefficiencies. By analyzing power quality metrics, harmonic distortions, and demand spikes, PME helps facility managers pinpoint energy waste sources such as inefficient HVAC systems, lighting, or standby loads. The tool’s demand charge optimization feature allows users to flatten load curves, reducing peak demand charges—a significant cost driver in commercial buildings.

Key functionalities include:


13. Automated alerting for abnormal energy consumption patterns, triggering investigations into equipment faults or operational inefficiencies.
14. Load profiling to correlate energy use with occupancy schedules, identifying underutilized spaces or equipment running during off-hours.
15. Peak shaving strategies via demand response (DR) signals, where PME integrates with building automation systems (BAS) to temporarily curtail non-critical loads during high-demand periods.

Example: A retail store using PME reduced peak demand charges by 18% by shifting non-essential loads (e.g., refrigeration pre-cooling) to off-peak hours, leveraging time-of-use (TOU) tariffs.

Demand Response Programs with AVEVA System Platform and Automated Curtailment Strategies

Schneider Electric’s AVEVA System Platform enables automated demand response (ADR) by integrating grid signals with building systems, ensuring compliance with utility incentives while maintaining operational continuity. The platform supports direct load control (DLC) and price-responsive DR, where buildings adjust consumption based on real-time grid conditions or market prices.

Implementation involves:


16. Automated curtailment triggers tied to ISO/RTO signals (e.g., PJM, CAISO) or utility DR events, such as emergency demand response programs (EDR).
17. Prioritization logic to curtail non-critical loads (e.g., lighting, non-essential HVAC) while preserving critical operations (e.g., IT, security).
18. Post-event analysis to validate energy savings and avoid penalties for non-compliance.

Key Formula for DR Savings:
Savings = (Peak Reduction × Demand Charge Rate) + (Energy Reduction × kWh Rate) – (Curtailment Costs)
Example: A manufacturing plant participating in a $15/kW demand charge program reduced peak demand by 500 kW, saving $7,500 per event while avoiding curtailment costs via pre-cooling strategies.

Best Practice: Sensors should be calibrated annually and placed away from direct sunlight, drafts, or heat sources to ensure ±0.5°C accuracy.

PID Tuning Protocols for Optimal Control
Proportional-Integral-Derivative (PID) tuning ensures the controller responds dynamically to system deviations. Schneider Electric’s M580/M340 supports auto-tuning and manual adjustment via EcoStruxure Control Expert software. The tuning process involves:
1. Proportional (P) Gain: Adjusts the controller’s immediate response to error (e.g., increasing P for faster correction but risking overshoot).
2. Integral (I) Gain: Eliminates steady-state error over time by accumulating past deviations (e.g., reducing I to prevent sluggishness).
3. Derivative (D) Gain: Predicts future error trends using rate-of-change data (e.g., increasing D to dampen oscillations).


Formula for PID Tuning:
\[ u(t) = K_p e(t) + K_i \int_0^t e(\tau) \, d\tau + K_d \frac{de(t)}{dt} \]
Where:


\( u(t) \) = Control output

\( e(t) \) = Error (setpoint − measured value)

\( K_p, K_i, K_d \) = Tuning constants

Commissioning and Validation
Post-installation, the system undergoes a commissioning phase to validate energy savings:

35. Baseline Energy Audit: Compare pre- and post-installation energy consumption using Schneider Electric’s StruxureWare Power Monitoring Expert.
