Abstract [en]

Following the societal electrification trend, airports face an inevitable transition of increased electric demand, driven by electric vehicles (EVs) and the potential rise of electric aviation (EA). For aviation, short-haul flights are first in line for fuel exchange to electrified transportation. This work studies the airport of Visby, Sweden and the effect on the electrical power system from EA and EV charging. It uses the measured airport load demand from one year’s operation and simulated EA and EV charging profiles. Solar photovoltaic (PV) and electrical battery energy storage systems (BESS) are modelled to analyse the potential techno-economical gains. The BESS charge and discharge control are modelled in four ways, including a novel multi-objective (MO) dispatch to combine self-consumption (SC) enhancement and peak power shaving. Each model scenario is compared for peak power shaving ability, SC rate and pay-back-period (PBP). The BESS controls are also evaluated for annual degradation and associated cost. The results show that the novel MO dispatch performs well for peak shaving and SC, effectively reducing the BESS’s idle periods. The MO dispatch also results in the battery controls’ lowest PBP (6.9 years) using the nominal economic parameters. Furthermore, a sensitivity analysis for the PBP shows that the peak power tariff significantly influences the PBP for BESS investment.

Abstract [en]

The Swedish solar farm market is expanding rapidly as ground-mounted solar plants are getting larger in size and number. This development inevitably leads to an increased land use change, which is the foremost cause of biodiversity loss. Along with a decrease in biodiversity, nature's supply of ecosystem services decreases, as well as chances to meet several (inter)national environmental and sustainable development goals. This study presents results of the Eco-Sun project, developing practical guidelines for the planning, construction and management of solar farms with a net zero, or net positive, impact on biodiversity and ecosystem services. It shows that biodiversity measures are present but limited in Swedish solar farms, while agrivoltaic crop cultivation is limited to one single site. In order to address environmental challenges and increase multiple land use, a step-by-step process is presented for the inclusion of biodiversity, agricultural and non-agricultural ecosystem services into the planning and design of ground-mounted solar PV.

Abstract [sv]

Denna handbok beskriver relevansen av och tillvägagångssättet att planera och förvalta solcellsparker att gynna biologisk mångfald och ekosystemtjänster, med särskild fokus på jordbruk. Med utgångspunkten i hänsynshierarkin beskrivs hur målet om netto noll eller netto positiv påverkan kan integreras i solcellsprojektens olika faser. Centralt är att placeringar på mark med höga naturvärden ska undvikas. Planeringsfasen för nya solcellsparker behöver ta avstamp i de lokala förutsättningarna avseende befintliga naturvärden, potentialen för jordbruk och sociala och rekreativa värden. Sedan ska solcellsparken utformas så att solelproduktion och biologisk mångfald, jordbruk och/eller andra ekosystemtjänster kan samexistera. Detta kan underlättas genom zonindelningar och val av lämplig solcellsmontering och lämpliga solcellspaneler. Även framtagande av skötselplaner i ett tidigt skede bidrar till en anläggning som har goda förutsättningar att skapa multifunktionella värden. Anläggningsfasen ska utföras så att minimal påverkan sker på naturen och marken, till exempel genom att undvika vissa årstider, att hålla skyddsavstånd och undvika markpackning. Driftfasen handlar om rätt skötsel, så att den önskade biologiska mångfalden kan frodas och/eller att jordbruket är produktivt och att de olika aktiviteter kan hanteras effektivt sida vid sida. För att inspirera och ge konkret guidning innehåller handboken åtgärdsbibliotek för ekovoltaiska system (d.v.s. kombinationer av ökad biologisk mångfald och reglerande, kulturella och/eller stödjande ekosystemtjänster med solcellsinstallationer) och agrivoltaiska system. Solcellstekniska lösningar och deras påverkan på förutsättningar för framförallt jordbruk, men även biologisk mångfald, beskrivs också i mer detalj i handboken.
