Energy Management Systems in Microgrids
Optimizing power flow and profitability with intelligent energy dispatch
What is an Energy Management System?
Energy Management Systems, often shortened as EMS, are advanced digital tools designed to monitor, control, and optimise the performance of power generation and consumption within microgrids. By integrating real-time data, predictive algorithms, and user-defined priorities, EMS enhances operational efficiency and maximises economic returns.
Core capabilities of Energy Management Systems
An EMS manages the flow of electricity with precision, ensuring optimal distribution and market participation. The core modules work together to achieve continuous energy optimisation.
Core logic
Calculates optimal energy flows based on user priorities
Power Management System (PMS)
Executes control signals to grid assets
Forecasting
Predicts energy production and consumption trends
Trading Engine
Integrates with markets to manage arbitrage and bids
Settlements Module
Handles profit-sharing and financial reconciliations
User Interface
Interactive dashboards for both operators and clients
Continuous optimisation with real-time data
Through real-time data analysis and automated energy dispatch, the EMS ensures consistent performance. This includes load balancing, storage decisions, and demand-side adjustments—especially in scenarios involving battery energy storage systems (BESS).
- Sales of excess energy production
- Arbitrage using battery storage
- Time shifting consumption patterns
- Ancillary services bidding
Short-Term Needs, Long-Term Goals
The Energy Management System is not just a short-term solution — it’s a strategic asset for long-term competitiveness in microgrid operations.
Short-Term Business Needs
- Day 0 operational readiness for early customers
- Enable basic optimisation and trading from launch
Long-term strategic goals
- Build world-class forecasting capabilities
- Develop EMS as IP-protected competitive edge
- Flexibility to adapt to future market & tech changes
Three pathways to deploy an Energy Management systems
Plexar Energy has evaluated three strategic models for EMS deployment. Each comes with trade-offs in speed, control, and long-term viability.
HBGT
- Quick implementation via existing relationships
- Limited IP ownership, vendor dependency
Modular System
- Trusted, tested components from known vendors
- Low customization, no access to source code
In-house Development
- Total control, IP ownership, and competitive differentiation
- High initial cost and development risk
How Energy Management systems benefit everyone
Whether serving the end-user or supporting the grid, EMS provides tangible benefits through smart energy balancing and cost-efficient operations.
Harmonizes demand and supply for cost efficiency
Smoothens peak load and injection profiles
Supports frequency regulation for grid operators
Profit sharing through optimisation agreements
Under an Optimisation Agreement, Plexar leverages EMS to direct and manage power flows. Any profits from optimisation are shared with the off-taker, aligning technical control with financial outcomes.
