As a deep practitioner in photovoltaic energy storage systems and power quality, Ying Tong will analyze how SVG (Static Var Generator) serves as the "voltage stabilizer" and "grid interaction hub" for PV-storage systems from problem-solving mechanisms and underlying physical principles. The following content is based on engineering validation and electromagnetic transient simulations: I. Core Problems Solved by SVG & Working Principles   Problem 1: Voltage Flicker/Overlimit Caused by PV Fluctuation   - Scenario:     Cloud shading causes a 10MW PV plant’s output to drop from 8MW to 1MW in 2 seconds → 10% voltage sag at PCC.   - SVG Solution:     - Principle:       SVG detects voltage sag in real-time and instantly injects capacitive reactive current (\(I_q\)) via IGBT full-bridge circuits, counteracting voltage drop from line inductive reactance.       Voltage compensation formula:       Delta U = frac{Q_{SVG} \cdot X_L}{U_n}     - (X_L): Line impedance (Ω)       - (U_n): Rated voltage (V)       Example: For a 7% voltage drop (400V→372V), SVG injects 2Mvar capacitive reactive power within 10ms, restoring voltage to 392V (error <2%).   - Control Logic:   Problem 2: Power Factor Mutation During ESS Mode Switching   - Scenario:     ESS switches from charging (absorbing reactive power) to discharging (generating reactive power) → PF jumps from 0.95 lag to 0.9 lead.   - SVG Solution:     - Principle:       SVG operates in bidirectional quadrants:       - When PCS absorbs reactive power (inductive), SVG generates capacitive reactive power       - When PCS generates reactive power (capacitive), SVG absorbs excess reactive power       Power factor correction formula:       Q_{comp} = PESS cdot (tanϕ1 - tanϕ2)     - PESS: ESS active power (kW)       - ϕ1, ϕ2): PF angles before/after compensation       Example: For a 2MW ESS switching modes, SVG toggles ±0.8Mvar within 5ms.   Problem 3: Resonance Risk in Weak Grids   - Scenario:     Parallel resonance between PV inverters and SVG at 650Hz → background harmonics amplified by 200%.   - SVG Solution:     - Principle:       SVG embeds active damping algorithm:       1. Detect resonance frequency via FFT (e.g., 650Hz)       2. Inject virtual resistance (R_virtual) into control loop:       3. Reshapes grid impedance to suppress resonance peak <3%.   II. SVG Hardware Operating Principles   Core Topology (Th...
