energy-systems
The energy-systems skill analyzes renewable energy integration, power systems, and storage optimization through resource assessment, grid modeling, and techno-economic evaluation. Deploy it when users discuss solar or wind installations, battery storage, grid dispatch, energy efficiency, levelized cost calculations, electric vehicles, or hydrogen systems, using methodologies including resource quantification, system sizing, dispatch optimization, and economic analysis with standard tools like NREL's SAM and Global Wind Atlas.

## When to Trigger Activate this skill when the user mentions: - Solar energy, photovoltaic, wind power, hydropower - Power grid, load balancing, dispatch optimization - Battery storage, lithium-ion, energy density, cycling - Energy efficiency, HVAC, building energy modeling - Techno-economic analysis, LCOE, payback period - Electric vehicles, charging infrastructure, V2G - Hydrogen economy, fuel cells, electrolysis ## Step-by-Step Methodology 1. **Define the energy system scope** - Specify system boundaries: single building, microgrid, regional grid, or national scale. Identify energy sources (solar, wind, fossil, nuclear, hydro), storage technologies, and demand profiles. 2. **Resource assessment** - For solar: analyze irradiance data (GHI, DNI, DHI), calculate capacity factor, account for degradation and soiling. For wind: analyze wind speed distributions (Weibull), compute power curves, assess turbulence intensity. Use TMY (Typical Meteorological Year) data or site-specific measurements. 3. **System modeling** - Size components: panels/turbines (capacity), inverters, batteries (energy and power), converters. Model energy balance: generation - consumption - storage - curtailment = grid exchange. Use hourly or sub-hourly time resolution. 4. **Grid integration** - Analyze grid interconnection requirements: voltage, frequency, power factor. Assess variability and ramping impacts. Model dispatch optimization (merit order, economic dispatch, unit commitment). Evaluate ancillary services potential. 5. **Storage analysis** - Characterize storage technology: energy density (Wh/kg), power density (W/kg), round-trip efficiency, cycle life, calendar life, self-discharge rate. Optimize sizing based on arbitrage value, peak shaving, or reliability requirements. 6. **Economic analysis** - Calculate LCOE (levelized cost of energy) with discount rate, capital costs, O&M, fuel costs, and lifetime. Compute NPV, IRR, and payback period. Include incentives (ITC, PTC, feed-in tariffs). Conduct sensitivity analysis on key assumptions. 7. **Environmental assessment** - Calculate avoided CO2 emissions using grid emission factors. Perform lifecycle emissions analysis (cradle-to-gate). Compare with conventional alternatives. ## Key Databases and Tools - **NREL (SAM, PVWatts, NSRDB)** - Solar and renewable energy tools - **Global Wind Atlas** - Wind resource data - **EIA / IEA** - Energy statistics and projections - **HOMER Energy** - Microgrid optimization - **OpenDSS** - Distribution system simulation - **PyPSA** - Open-source power system analysis ## Output Format - Resource assessment as tables: annual/monthly capacity factor, energy yield (kWh/kWp). - System diagram with component sizes, power flows, and energy balance. - LCOE breakdown: capital, O&M, fuel, financing costs per kWh. - Economic results as NPV, IRR, payback period with sensitivity tornado chart. - Time series plots: generation, demand, storage state-of-charge, grid exchange. ## Quality Checklist - [ ] Resource data source and time resolution specified - [ ] System losses itemized (inverter, wiring, degradation, soiling, curtailment) - [ ] Discount rate and financial assumptions documented - [ ] Storage degradation and replacement costs included in economics - [ ] Grid emission factor source and year specified - [ ] Sensitivity analysis covers key uncertainties (resource, cost, discount rate) - [ ] Units consistent (kW vs. kWh, AC vs. DC clearly distinguished) - [ ] Comparison with alternatives provided for context
Set up and use 1Password CLI (op). Use when installing the CLI, enabling desktop app integration, signing in (single or multi-account), or reading/injecting/running secrets via op.
Transparent, rigorous research with full methodology — not a black-box API wrapper. Conducts exhaustive investigation through mandated 2-cycle research per theme, APA 7th citations, evidence hierarchy, and 3 user checkpoints. Self-contained using native OpenClaw tools (web_search, web_fetch, sessions_spawn). Use for literature reviews, competitive intelligence, or any research requiring academic rigor and reproducibility.
# Academic Literature Search — 学术文献检索与引用管理
Route plain-language requests for Pi, Claude Code, Codex, OpenCode, Gemini CLI, or ACP harness work into either OpenClaw ACP runtime sessions or direct acpx-driven sessions ("telephone game" flow). For coding-agent thread requests, read this skill first, then use only `sessions_spawn` for thread creation.
Manage Apple Notes via the `memo` CLI on macOS (create, view, edit, delete, search, move, and export notes). Use when a user asks OpenClaw to add a note, list notes, search notes, or manage note folders.
Manage Apple Reminders via remindctl CLI (list, add, edit, complete, delete). Supports lists, date filters, and JSON/plain output.
Write articles, guides, blog posts, tutorials, newsletter issues, and other long-form content in a distinctive voice derived from supplied examples or brand guidance. Use when the user wants polished written content longer than a paragraph, especially when voice consistency, structure, and credibility matter.
Search and retrieve preprints from arXiv via the Atom API. Use this skill when searching for papers in physics, mathematics, computer science, quantitative biology, quantitative finance, statistics, electrical engineering, or economics by keywords, authors, arXiv IDs, date ranges, or categories.
