jailcd2020088: Energy and Economic Performance Analysis of the Renewable Energy to Heat for Residential Heating Supply: a Case Study in Qingdao Area

Abstract

Higher shares of fluctuating renewable generation may lead to curtailment of surplus production considering grid security. One approach for reducing curtailment of renewable energies is to link residential district heating and power supply system. The customer also can import energy from grid when renewable energy is in low-level. By this way, we can get win-win situation-renewable energy could be fully utilized and residents can reduce the expenditure in power-to-heat. To analyze the matching of variable renewable energy renewable production profiles is important. Therefore, we need to analyze the influence of heat load and explore the feature of fluctuation of the renewable energy. We also need to analyze the Influence factor of generating electricity and assess the matched situation. As a result, produce the feasibility research and give the available advises to integrate the renewable energy and traditional energy to heat for residential heating supply.
